Reverse number(logic)
------
First Approach :=
void reverseMethod(int n)
{
String str="";
int temp=0;
while(n>0)
{
temp=n%10;
n=n/10;
str=str+""+temp;
}
System.out.println(str);
}
-----
Second Approach :=
void reverseMethod(int n)
{
int temp=0;
int rev=0;
while(n>0)
{
temp=n%10;
n=n/10;
rev=rev*10+temp;
}
System.out.println(rev);
}

In first, at least we do not required to remember that formula.
