Java PrintWriter print(long)用法及代码示例

Java中的PrintWriter类的print(long)方法用于在流上打印指定的long值。该long值用作参数。此方法类似于write(String.valueOf(long))，其中String.valueOf(long)返回以字节为单位的数字，并借助write()方法将这些字节添加到Stream上。

用法:

public void print(long longValue)

参数：此方法接受强制参数longValue，该参数是要写入流中的long值。

返回值：此方法不返回任何值。

下面的方法说明了print(long)方法的用法方式：

示例1:

// Java program to demonstrate 
// PrintWriter print(long) 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 long value '4' 
            // to this stream using print() method 
            // This will put the longValue in the 
            // stream till it is printed on the console 
            printr.print(4); 
  
            printr.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

输出：

示例2:

// Java program to demonstrate 
// PrintWriter print(long) 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 long value '65' 
            // to this stream using print() method 
            // This will put the longValue in the 
            // stream till it is printed on the console 
            printr.print(65); 
  
            printr.flush(); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

输出：
