Java PrintWriter println(int)方法及示例

Java中PrintWriter类的println(int)方法用于在流中打印指定的int值，然后断开该行。这个int值被作为一个参数。

语法。

public void println(int intValue)

参数。这个方法接受一个强制性参数intValue，它是要写入流的int值。

返回值。该方法不返回任何值。

以下方法说明了println(int)方法的工作。

程序1:

// Java program to demonstrate
// PrintWriter println(int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter printr
                = new PrintWriter(System.out);
  
            // Print the int value '4'
            // to this stream using println() method
            // This will put the intValue in the
            // stream till it is printed on the console
            printr.println(4);
  
            printr.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

4

程序2。

// Java program to demonstrate
// PrintWriter println(int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter printr
                = new PrintWriter(System.out);
  
            // Print the int value '65'
            // to this stream using println() method
            // This will put the intValue in the
            // stream till it is printed on the console
            printr.println(65);
  
            printr.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

65
