In this tutorial how to create a program to print reverse of a number in Core Java is shown.
Code:
ReverseNo.java
class ReverseNo
{
public static void main(String args[])
{
int number=Integer.parseInt(args[0]),sum=0,r,copyn;
copyn=number;
while(copyn>0)
{
r=copyn%10;
sum=(sum*10)+r;
copyn/=10;
}
System.out.println(“The reverse of “+number+” is “+sum);
}
}
