Java中的 PrintWriter print(int) 方法及示例

Java中PrintWriter类的print(int)方法用于在流上打印指定的 int 值。这个 int 值被当作一个参数。

句法:

public void print(int intValue)

参数:此方法接受一个强制参数intValue ,它是要写入流的 int 值。

返回值:此方法不返回任何值。

下面的方法说明了 print(int) 方法的工作:

方案一:

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

方案二:

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