Java CharArrayWriter writeTo()用法及代码示例

Java中CharArrayWriter类的writeTo(Writer)方法用于将CharArrayWriter的内容写入另一个字符流。

public void writeTo(Writer out)
             throws IOException

参数：此方法接受一个代表输出流的参数，该输出流是目标流。返回值：此方法不返回任何值。异常：如果发生I /O错误，此方法将引发IOException。下面的程序演示了writeTo(Writer)方法在IO包的CharArrayWriter类中：程序1：

Java

// Java program to illustrate 
// CharArrayWriter writeTo(Writer) method 
  
import java.io.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws IOException 
    { 
  
        // Create charArrayWriter 
        CharArrayWriter charArrayWriter 
            = new CharArrayWriter(); 
  
        String str = "GEEKS"; 
  
        charArrayWriter.write(str); 
  
        // Create outputStream 
        CharArrayWriter out 
            = new CharArrayWriter(); 
  
        charArrayWriter.writeTo(out); 
  
        // print the outputStream 
        System.out.println( 
            out.toString()); 
    } 
}

输出：

GEEKS

程序2:

Java

// Java program to illustrate 
// CharArrayWriter writeTo(Writer) method 
  
import java.io.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws IOException 
    { 
  
        // Create charArrayWriter 
        CharArrayWriter charArrayWriter 
            = new CharArrayWriter(); 
  
        charArrayWriter.write("GEEKSFORGEEKS"); 
  
        // Create outputStream 
        CharArrayWriter out 
            = new CharArrayWriter(); 
  
        charArrayWriter.writeTo(out); 
  
        // print the outputStream 
        System.out.println( 
            out.toString()); 
    } 
}

输出：

GEEKSFORGEEKS
