Java Program to Find Reverse of Given Number Using Class
Write a Java program to define a class having one 3-digit number, num as data member. Initialize and display reverse of that number..
Source Code
public class Reverse {
int num,r=0,s=0;
Reverse(int n) {
num = n;
}
void calReverse() {
System.out.print("Reverse of number " + num + " is = ");
while(num>0) {
r=num%10;
s=(s*10)+r;
num=num/10;
}
System.out.println(s);
}
public static void main(String[] args) {
Reverse r1 = new Reverse(786);
r1.calReverse();
}
}
Output
Reverse of number 786 is = 687
