程序 1:

// Java program to demonstrate
// PrintWriter write(int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);
  
            // Write the character '0' to this writer
            // using write() method
            // This will put the string in the stream

            writer.write(48);

        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

0

程序2。

// Java program to demonstrate
// PrintWriter write(int) method
