Java PrintStream println(long)用法及代碼示例

Java中PrintStream類的println(long)方法用於在流上打印指定的long值，然後換行。該long值用作參數。

用法:

public void println(long longValue)

參數：此方法接受強製參數longValue，該參數是要寫入流中的long值。

返回值：此方法不返回任何值。

下麵的方法說明了println(long)方法的用法方式：

示例1:

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

輸出：

示例2:

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