Java CharArrayWriter toString()方法及示例

Java中 CharArrayWriter 类的 toString() 方法将给定的输入数据转换为一个字符串。

语法:

public String[] toString()

参数： 该方法不接受任何参数。

返回值： 该方法返回一个输入数据的副本。

下面的程序说明了上述方法。

程序1 :

// Java program to illustrate the
// above mentioned method
 
import java.io.*;
 
public class GFG {
    public static void main(String[] args)
        throws IOException
    {
 
        // Initializing String Witer
        CharArrayWriter geek_writer1
            = new CharArrayWriter();
 
        CharSequence char_sq1 = "geeks for + ";
        CharSequence char_sq2 = "geeks";
 
        // Use of append(CharSequence char_sq)
        geek_writer1.append(char_sq1);
        geek_writer1.append(char_sq2);
 
        // Convert it into string and print
        System.out.println("String : "
                           + geek_writer1.toString());
    }
}

输出

String : geeks for + geeks

程序2

// Java program to illustrate the
// above mentioned method
 
import java.io.*;
 
public class GFG {
    public static void main(String[] args)
        throws IOException
    {
 
        // Initializing String Witer
        CharArrayWriter geek_writer1
            = new CharArrayWriter();
 
        CharSequence char_sq1 = "Gopal ";
        CharSequence char_sq2 = "Dave";
 
        // Use of append(CharSequence char_sq)
        geek_writer1.append(char_sq1);
        geek_writer1.append(char_sq2);
 
        // Convert it into string and print
        System.out.println("String : "
                           + geek_writer1.toString());
