StringWriter 用 Java 写(String)方法，示例

原文:https://www . geesforgeks . org/stringwriter-write string-in-Java-method-with-examples/

Java 中 StringWriter 类的 write(String) 方法用于在流上写入指定的字符串。该字符串值被视为参数。

语法:

public void write(String string)

参数:该方法接受一个强制参数字符串，它是要写入流中的字符串。

返回值:此方法不返回值。

下面的程序说明了写(字符串)方法的工作原理:

程序 1:

// 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);
        }
    }
}

Output:

GeeksForGeeks

程序 2:

// 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);
        }
    }
}

Output:

GFG
