Java Program to output fixed number of array elements in a line

To output fixed number of array elements in a line, we should check for a condition and if that is true, we should place System.out.println(); properly to get a line and the process goes on.

Here, we will display 5 elements in a line. At first, create a new integer array and add some elements −

int[] list = new int[50];
for (int i = 0; i < list.length; i++) {
   list[i] = (int)(i + 20);
}

Now, declare a new variable and initialize it to 0. This variable is checked in a for loop that loops until the length of the array. A new line is set after 5 elements are displayed −

int output = 0;
for (int i = 0; i < list.length; i++) {
   if (output == 5) {
      System.out.println();
      output = 0;
   }
   System.out.print(list[i] + ", ");
   output++;
}

Example

 Live Demo

public class Demo {
   public static void main(String[] args) {
      int[] list = new int[50];
      for (int i = 0; i < list.length; i++) {
         list[i] = (int) (i + 20);
      }
      int output = 0;
      for (int i = 0; i < list.length; i++) {
         if (output == 5) {
            System.out.println();
            output = 0;
         }
         System.out.print(list[i] + ", ");
         output++;
      }
   }
}
