Java PrintWriter println(Object)方法及示例

Java中PrintWriter类的println(Object)方法用于在流中打印指定的对象，然后断开该行。这个对象被当作一个参数。

语法。

public void println(Object object)

参数。该方法接受一个强制性的参数对象，它是要在流中打印的对象。

返回值。该方法不返回任何值。

以下方法说明了println(Object)方法的工作。

程序 1:

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

程序2。

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

输出:

GFG
