Java Writer write(char[])方法及示例

Java中Writer类的write(char[])方法是用来在流中写入指定的字符数组。这个字符数组被作为一个参数。

语法。

public void write(char[] charArray)

参数。该方法接受一个强制性参数charArray，它是要写入流中的字符数组。

返回值。这个方法不返回任何值。

下面的方法说明了write(char[])方法的工作。

程序 1:

// Java program to demonstrate
// Writer write(char[]) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a Writer instance
            Writer writer
                = new PrintWriter(System.out);
  
            // Get the character array
            // to be written in the stream
            char[] charArray = { 'G', 'e', 'e', 'k', 's',
                                 'F', 'o', 'r',
                                 'G', 'e', 'e', 'k', 's' };
  
            // Write the charArray
            // to this writer using write() method
            // This will put the charArray in the stream
            // till it is printed on the console
            writer.write(charArray);
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

程序2。

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

输出:
