What is concatenation? On which data type is concatenation performed?

Determine the output of the following program.

public class Test
{
    public static void main(String[] args) 
    {
        int a = 1, b = 2;
        System.out.println("Output1: " + a + b);
        System.out.println("Output2: " + (a + b));
    }
}

Determine the output of the following program.

public class PredictOutput1
{
  public static void main(String args[])
  {
       int a = 4, b = 2, c = 3;
       System.out.println("Output 1: " + (a = b * c));
       System.out.println("Output 2: " + (a = (b * c)));
  }
}
