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.
4.
- 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
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
