Java中的 PrintWriter write(int) 方法和示例

Java中PrintWriter类的write(int)方法用于在流上写入指定的字符。此字符是使用作为整数值传递的字符的 ASCII 值指定的。这个整数值被当作一个参数。

句法：

public void write(int ascii)

参数：此方法接受一个强制参数ascii ，它是要写入流的字符的 ASCII 值。

返回值：此方法不返回任何值。

下面的方法说明了 write(int) 方法的工作：

方案一：

// Java program to demonstrate
// PrintWriter write(int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);
  
            // Write the character '0' to this writer
            // using write() method
            // This will put the string in the stream
            // till it is printed on the console
            writer.write(48);
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出：

0

方案二：

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

输出：

A
