2. Comparing Two Numbers This is a very simple example of Java that teaches you the method of comparing two numbers and finding out the greater one . 3.

First of all, name a class "Comparing" and take two variables in this class (ie, a & b). Here we have taken a=5 and b=10,

Now we have to find out whether a=b, a>b or b>a.

To find out this apply if and else condition one by one.

Now apply the condition "if (a=b)", if this satisfies then print both are equal.

If this doesn't satisfy, then check whether a>b by applying the "else if" condition and print the message "a is greater than b.

Again this doesn't satisfy then 'else' condition as shown in the example will show that b is greater than a.

code of the program:

class Comparing{ publicstaticvoid main(String[]args){ int a=5,b=10; if (a==b){ System.out.println("Bothareequal"); } elseif (a>b){ System.out.println("aisgreaterthanb"); } else { System.out.println("bisgreaterthana"); } } }

5. How to compile & run

Compiling:

javac Comparing.java

Run:

java Comparing

Out put:

bisgreaterthana

6. Program to list all even numbers between two numbers

This is a program for listing out all the even numbers between two numbers.

7.

For this first create a class namedAllEvenNumunder the java.io package. Now use the try/catch exception to avoid any kind of input error.

After this create a buffer class in which all the input data are stored and modified. Then give message as to "Enter number" in theSystemmethod.

As we have to find out all the even numbers between 1 and the input number, define an integer variable 'num'.

Now applyParseIntmethod that parses the string character into decimal integer.

Applyforloop in which define an integer i=1 and i
