A **Jumping Number** is a number in which each adjacent digit differs by only 1.

For example, 76789 is a Jumping Number.

Also note that all the one-digit numbers are considered to be Jumping Numbers.

Write a program in Java to input a positive integer and check whether it is a Jumping Number.

Display a suitable message accordingly.

```
import java.io.*;
class Jumping{
public static void main(String args[])throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter a positive integer: ");
int num = Math.abs(Integer.parseInt(br.readLine()));
int copy = num;
boolean status = true;
int diff = 0;
while(num != 0){
int d1 = num % 10;
num /= 10;
if(num != 0){
int d2 = num % 10;
if(Math.abs(d1 - d2) != 1){
status = false;
break;
}
}
}
if(status)
System.out.println(copy + " is a jumping number.");
else
System.out.println(copy + " is NOT a jumping number.");
}
}
```
