Java Writer write(int)方法及实例

Java中Writer类的write(int)方法是用来在写入器上写入指定的字节值。这个字节值是用作为整数值传递的字节值的ASCII值来指定的。这个整数值被当作一个参数。

语法。

public void write(int ascii)

参数。这个方法接受一个强制性的参数ascii，它是要写在写入器上的字节值的ASCII值。

返回值。这个方法不返回任何值。

下面的方法说明了write(int)方法的工作。

程序 1:

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

输出:

0

程序2。

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

输出:

A
