I can't describe what's my problem

Hi,
I’m creating an app for fun on my phone and I got that… :

  • [ means array, L means object and java.lang.String means String.
  • So those are arrays of String objects.
  • We can display 1 in Java like this: System.out.println(new String[] {});
  • Alternatively in Processing like this: println(new String[] {}.toString());

Hi.
It seems like you want to print out the text of some string arrays but you printed the array instead of the strings inside.
Your code might look like this:

String[][] somestrings = new String[1][3];
somestrings[0][0] = "hello";
somestrings[0][1] = "im";
somestrings[0][2] = "max";
println(somestrings); // I guess you didn't use println but the idea is the same

This should have prints the array instead of the strings.

However you really should use something like this:

String[][] somestrings = new String[1][3];
somestrings[0][0] = "hello";
somestrings[0][1] = "im";
somestrings[0][2] = "max";
for (int i = 0; i < somestrings.length; i++) {
  for (int j = 0; j < somestrings[i].length; j++) {
    println(somestrings[i][j]); // I guess you didn't use println but the idea is the same
  }
}

PS: As I just found out the second for-loop is not strictly necessary in this example.

Yes, of course: but this post has not any reason to be tagged as “android”! - It is exactly the same in Java…
