The class is based on the basic principle of last-in-first-out. In addition to the basic push and pop operations, the class provides three more functions of empty, search and peek.
The class can also be said to extend Vector and treats the class as a stack with the five mentioned functions. The class can also be referred to as the subclass of Vector.
This diagram shows the hierarchy of Stack class:. The class supports one default constructor Stack which is used to create an empty stack. Below program shows few basic operations provided by the Stack class:.

Here is the code to calculate the average of N numbers or average of 2 or 3 numbers. The following code has been written in three different ways, using standard values, using do whilerecursion, command line arguments, creating a separate class, user-defined method.
How to calculate the average of N Numbers? The calculation of the average of N numbers ins quite simple: Here is the formula for it. Hope you get to understand. The following program can be applied for either average of two numbers or average of three numbers, or an average of N numbers. In the case of all N number. Just replace the SOP with the above-given formula. The following code has been written in five different ways for both programs along with the sample output for an average of 2 numbers and average of three numbers or N numbers, in using standard valueswhile loop, for loop, do while loop, command line arguments, user define method, creating a separate class.

Copyrighted Protected.In our previous blogs — Java tutorial and object-oriented programmingwe have discussed the various fundamental concepts of Java and have built a strong foundation in Java. In this blog, we will be discussing about a new concept, Java Str ing.
S tring is a sequence of characters. The java. String class is used to create string object. Now, let us understand the concept of Java String pool. In this, whenever a new object is created, String pool first checks whether the object is already present in the pool or not.
Refer to the diagrammatic representation for better understanding:. In the above image, two Strings are created using literal i.
Before we go ahead, One key point I would like to add that unlike other data types in Java, Strings are immutable. By immutable, we mean that Strings are constant, their values cannot be changed after they are created.
Because String objects are immutable, they can be shared. For example:. Let us now look at some of the inbuilt methods in String class.
This program shows the comparison between the various string. If the java String is Empty, it returns true else false. If it exists, then removes the spaces and return the omitted string. Java String ValueOf : This method converts different types of values into string. Using this method, you can convert int to string, long to string, Boolean to string, character to string, float to string, double to string, object to string and char array to string.
In the above code, it concatenates the Java String and gives the output — Java String replace : The Java String replace method returns a string, replacing all the old characters or CharSequence to new characters. There are 2 ways to replace methods in a Java String. In the above code, the first two statements will return true as it matches the String whereas the second print statement will return false because the characters are not present in the string.
In the above code, the first statement will return true because the content is same irrespective of the case. Java StringGetBytes : The Java string getBytes method returns the sequence of bytes or you can say the byte array of the string. If the length of the String is 0, it returns true else false. This is not the end. There are more Java String methods that will help you make your code simpler. Since, Java String is immutable and final, so a new String is created whenever we do String manipulation.
Let us understand the difference between these two utility classes:. I would recommend you to try all the Java String examples.

WAP for Java developers
Handheld wireless devices, however, have a more constrained computing environment compared to desktop computers. Handheld devices tend to have less memory, less powerful CPUs, different input devices, and smaller displays.
Further, wireless networks have less bandwidth and more latency compared to wired computer networks. WAP, the Wireless Application Protocol, was designed to take advantage of the several data-handling approaches already in use. WAP is meant for cellular phones, and Java aims at more sophisticated network terminals. The WAP platform is an open specification that addresses wireless network characteristics by adapting existing network technologies and introducing new ones where appropriate to the special requirements of handheld wireless devices.
To facilitate the delivery of Internet data to wireless devices will certainly lead to the introduction of new technology. For example, wireless devices have small screens compared to desktop computers, and therefore HTML which is visually rich is not appropriate for small screens. The small screen and the computing power, which is increasing, represent a limiting factor in running complicated Java applications with intensive graphics.
However, efforts are being made for having a compact subset of the Java language suitable for mobile applications. But first, I describe the WAP platform and how it incorporates several technologies that are similar to existing ones but that have been designed specifically for wireless devices. The WAP standard defines two essential elements: an end-to-end application protocol and an application environment based on a browser.
The application protocol is a communication protocol stack that is embedded in each WAP-enabled wireless device also known as the user agent. The server side implements the other end of the protocol, which is capable of communicating with any WAP client. Figure 1 illustrates an example structure of a WAP network. In Figure 1, the client communicates with the WAP gateway in the wireless network.
Figure 3 illustrates this stack protocol and also shows a comparison to a Web-based protocol stack. The WAP protocol stack has four layers: session layer, transaction layer, security layer, and datagram layer. Based on these differences, WML provides a smaller, telephony-aware set of tags that make it more appropriate than HTML for handheld wireless terminals.
Similar to HTML, though, with WML you can give the user input options and specify how the user agent should respond when, for example, the user presses a key. The basic unit of WML is the card that specifies a single interaction between the user and the user agent. Multiple cards are grouped together in decks.
A deck is the topmost element of a WML document. When the user agent receives a deck by downloading the complete deckit activates only the first card in the deck.

Listing 1 shows a sample WML document with a single card:.Hi, We can print triangle using two loops only. Pls anyone can do this???

Program Example.In Java, arrays are first class objects. In the above program, arr1 and arr2 are two references to two different objects. How to compare array contents? A simple way is to run a loop and compare elements one by one. Java provides a direct method Arrays. Actually, there is a list of equals methods in Arrays class for different primitive types int, char. How to Deep compare array contents? As seen above, the Arrays. Now the questions, what if the arrays contain arrays inside them or some other references which refer to different object but have same values.
For example, see the following program. So Arrays. Java provides another method for this Arrays. How does Arrays. It compares two objects using any custom equals methods they may have if they have an equals method implemented other than Object. If not, this method will then proceed to compare the objects field by field, recursively. As each field is encountered, it will attempt to use the derived equals if it exists, otherwise it will continue to recurse further.
