Usage

From source file:Main.java

public static void main(String[] args) {
    String s = "from java2s.com.";

    // create a new PrintStream
    PrintStream ps = new PrintStream(System.out);

    // print a string
    ps.println(s);// w w  w . j a v a 2  s .  c  o m

    // check for errors and print
    ps.print(ps.checkError());
    ps.flush();
    ps.close();
