Java PrintWriter write(String)方法及示例

Java中PrintWriter类的write(String)方法用于在流中写入指定的字符串。这个字符串的值被作为参数使用。

语法。

public void write(String string)

参数。该方法接受一个强制性参数字符串，即要写入流中的字符串。

返回值。该方法不返回任何值。

下面的方法说明了write(String)方法的工作。

程序1:

// Java program to demonstrate
// PrintWriter write(String) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);
  
            // 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");
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:

GeeksForGeeks

程序2。

// Java program to demonstrate
// PrintWriter write(String) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a PrintWriter instance
            PrintWriter writer
                = new PrintWriter(System.out);
  
            // 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");
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
