## Java Basic: Exercise-98 with Solution

Write a Java program to check if the value 20 appears three times and no 20’s are next to each other in an given array of integers.

Pictorial Presentation: Sample Solution:

Java Code:

``````import java.util.*;
import java.io.*;
public class Exercise98 {
public static void main(String[] args)
{
int[] array_nums = {10, 20, 10, 20, 40, 13, 20};

int count = 0, result =0;

if(array_nums.length >= 1 && array_nums == 20)
count++;

for(int i = 1; i < array_nums.length; i++) {
if(array_nums[i - 1] == 20 && array_nums[i] == 20)
{
System.out.printf( String.valueOf(false));
result = 1;
}
if(array_nums[i] == 20)
count++;
}

if (result==0)
{
System.out.printf( String.valueOf(count == 3));
}
System.out.printf("\n");
}
}
```
```

Sample Output:
