Java中的 PrintStream print(long) 方法和示例

Java中PrintStream类的print(long)方法用于在流上打印指定的 long 值。这个长值被作为一个参数。

句法：

public void print(long longValue)

参数：此方法接受一个强制参数longValue ，它是要写入流的长值。

返回值：此方法不返回任何值。

以下方法说明了 print(long) 方法的工作原理：

方案一：

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

输出：

4

方案二：

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

输出：

65
