java System.out.println() strange behavior long string

Question

Can somebody explain me why this code does not print the numbers?

      String text = new String("SomeString");
      for (int i=0; i<1500; i++)          


        

Answer 1

String.concat() accepts a String parameter.

If you add "a number and a character" you are adding a string because the + operator understands you are chaining String and numeric data.

Anyway code runs fine to me, numbers appended till 1499 as expected.
