Create PrintWriter from System.out


import java.io.PrintWriter;

public class Main {

  public static void main(String args[]) throws Exception {

    PrintWriter pw = new PrintWriter(System.out);

    pw.println(true);
    pw.println('A');
    pw.println(500);
    pw.println(40000L);
    pw.println(45.67f);
    pw.println(45.67);
    pw.println("Hello");
    pw.println(new Integer("99"));

    pw.close();
  }
}

The output:


true
A
500
40000
45.67
45.67
Hello
99
