Question

For example, I have an array of type int and size 3, it has elements 1, 2, 3 When I try to print it in JOptionPane with loops, it makes three different panes.

When I try:

JOptionPane.showMessageDialog( null, array );

It gives garbage values.

I have searched everywhere but I couldn’t find a solution. How do I display the array in an option pane?

Answer 1

Use Arrays.toString () as :

    int [] arr = new int [3];
    arr[0]=1;
    arr[1]=2;
    arr[2]=3;

    JOptionPane.showMessageDialog(null, Arrays.toString(arr));
