In this example, we will use Math.nextAfter() to get the floating-point number adjacent to the first argument in the direction of the second argument.

### Source Code

```
package com.beginner.examples;
public class NextAferExample {
public static void main(String[] args){
//return the floating-point number adjacent to the first argument in the direction of the second argument.
double a = -10.8;
int d1 = 5;
double b = 0;
int d2 = 6;
double c = 2.01;
int d3 = 7;
System.out.println("nextAfter of " + a + " in the direction of " + d1 + " is: " + Math.nextAfter(a, d1));
System.out.println("nextAfter of " + b + " in the direction of " + d2 + " is: " + Math.nextAfter(b, d2));
System.out.println("nextAfter of " + c + " in the direction of " + d3 + " is: " + Math.nextAfter(c, d3));
}
}
```

Output:

```
nextAfter of -10.8 in the direction of 5 is: -10.799999999999999
nextAfter of 0.0 in the direction of 6 is: 4.9E-324
nextAfter of 2.01 in the direction of 7 is: 2.0100000000000002
