参数：此方法接受强制性参数对象，该对象是要在Stream中打印的对象。

返回值：此方法不返回任何值。

下面的方法说明了println(Object)方法的用法：

示例1:

// Java program to demonstrate 
// PrintStream println(Object) method 
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(System.out); 
  
            // Get the char[] object 
            // to be printed in the stream 
            char[] object = { 'G', 'e', 'e', 'k', 's', 
                              'F', 'o', 'r', 
                              'G', 'e', 'e', 'k', 's' }; 
  
            // print the object 
            // to this stream using print() method 
            // This will put the object in the stream 
            // till it is printed on the console 
            stream.println(object); 
  
            stream.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

            // Create a PrintStream instance 
            PrintStream stream 
                = new PrintStream(System.out); 
  
            // Get the String Object 
            // to be printed in the stream 
            String object = "GFG"; 
  
            // print the object 
            // to this stream using print() method 
            // This will put the object in the stream 
            // till it is printed on the console 
            stream.println(object); 
  
            stream.flush();
