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.
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.
