Java中的 StringWriter write(String) 方法及示例

Java中StringWriter类的write(String)方法用于在流上写入指定的String。这个字符串值被当作一个参数。

句法：

public void write(String string)

参数：此方法接受一个强制参数字符串，该字符串是要写入 Stream 的字符串。

返回值：此方法不返回任何值。

下面的程序说明了 write(String) 方法的工作：

方案一：

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

输出：

GeeksForGeeks

方案二：

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

输出：

GFG
