Java: Multidimensional Array

Question

I'm doing multidimensional arrays that will print an array of names of at least 2 with corresponding age and salary following the input from user. But when I run the program it is giving me null content. Below is my code. Your help would be highly appreciated.

import java.util.Scanner;
public class Employee {
 public static void main(String [] args) {
 Scanner input = new Scanner(System.in);
 String employeeList [][] = new String [2][3];
 // populating
 for (int i=0; i<employeeList.length; i++){
 System.out.println("Employee #" + (i+1));
 for (int j=0; j<employeeList[i].length; j++){
 System.out.print("Name\t:");
 employeeList [i][j] = input.nextLine(); 
 System.out.print("Age\t:");
 employeeList [i][j]= input.nextLine();
 System.out.print("Salary\t:");
 employeeList [i][j]= input.nextLine();
 break; 
 } 
 }
 //System.out.println();
 //System.out.println();
 //displaying
 System.out.printf("%15s%15s%15s\n", "NAME", "AGE", "SALARY");
 for (int i=0; i<employeeList.length; i++){
 for (int j=0; j<employeeList[i].length; j++){
 System.out.printf("%15s", employeeList[i][j]);
 }
 System.out.println();
 }
 }
}

• Maarten Bodewes: Why does the code contain a break?

Answer 1

The inner loop makes no sense, since you store the name, age and salary in the first column (employeeList[i][0]), which means the salary will overwrite the rest of the input.

You want to store each input in a different column of the current row of the array.

Just use a single loop :

for (int i=0; i<employeeList.length; i++){
 System.out.println("Employee #" + (i+1));
 System.out.print("Name\t:");
 employeeList [i][0] = input.nextLine(); 
 System.out.print("Age\t:");
 employeeList [i][1] = input.nextLine();
 System.out.print("Salary\t:");
 employeeList [i][2] = input.nextLine();
}
