reverse integer in java code example
Example 1: reverse number in java
public class ReverseNumber {
public static void main(String[] args) {
int num = 1234, reversed = 0;
while(num != 0) {
int digit = num % 10;
reversed = reversed * 10 + digit;
num = num / 10;
}
System.out.println("Reversed Number: " + reversed);
}}
Example 2: java code to reverse an integer
public class ReverseNumberExample1
{
public static void main(String[] args)
{
int number = 987654, reverse = 0;
while(number != 0)
{
int remainder = number % 10;
reverse = reverse * 10 + remainder;
number = number/10;
}
System.out.println("The reverse of the given number is: " + reverse);
}
}
Example 3: 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 4: reverse a integer in java
while(num != 0)
{
int digit = num % 10;
reversed = reversed * 10 + digit;
num /= 10;
}
Example 5: how to reverse a number in java
int rev= 0;
while(num > 9)
{
rev= rev*10 + num%10;
num/= 10;
}
