Chapter: Collections Last Updated: 22-07-2016 07:49:10 UTC

Program:

            /* ............... START ............... */
                
public class JavaParallelArray {
	public static void main(String[] args) {

		int[] id = { 6373, 3838, 1234 };
		String[] name = { "John", "Mark", "Peter" };
		String[] dept = { "IT", "Pharmacy", "Produce" };
		double[] pay = { 12.50, 13.75, 9.78 };

		/*
		 * ---------------------------------------------- Print the information
		 * in the parallel arrays ----------------------------------------------
		 */
		System.out.println("ID    Name        Department  Pay");
		System.out.println("----  ----------  ----------  -----");
		for (int i = 0; i < id.length; i++) {
			System.out.printf("%04d  ", id[i]);
			System.out.printf("%-10s  ", name[i]);
			System.out.printf("%-10s  ", dept[i]);
			System.out.printf("%5.2f", pay[i]);
			System.out.println();
		}
	}
}
                /* ............... END ............... */
        

Output

ID    Name        Department  Pay
----  ----------  ----------  -----
6373  John        IT          12.50
3838  Mark        Pharmacy    13.75
1234  Peter       Produce      9.78

Notes:

  • A parallel array is a data structure for representing arrays of records. Values located at the same index in each array are implicitly the fields of the same record.
