reverse a number by for loop code example
Example 1: reverse for loop
for (int i = myArray.Length - 1; i >= 0; i--)
{
// Do something ...
}
Example 2: reverse a number using mathematical operations in java
//continue to loop until a value is equal to 0
public class ReverseNum{
public static void main(String[] args {
int a = 543;
int reverse = 0;
while(a!=0){ //itera the process
int digit = a%10; //isolate the last digit number
reverse = digit + (reverse*10); //append last digit to reverse
a=a/10; // remove the last digit from number
}
System.out.println(reverse);
} }
Example 3: how to reverse a number in java
int rev= 0;
while(num > 9)
{
rev= rev*10 + num%10;
num/= 10;
}
