下面的方法说明了print(String)方法的工作。

程序1:

// Java program to demonstrate
// PrintWriter print(String) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);
  
            // Print the String value 'GeeksForGeeks'
            // to this stream using print() method
            // This will put the StringValue in the
            // stream till it is printed on the console
            writer.print("GeeksForGeeks");
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

GeeksForGeeks

            writer.print("GFG");
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
