Java –在字符串中添加新行

喜欢ヅ旅行 2023-02-15 05:08 7阅读 0赞

不同的操作系统具有不同的新行或行分隔符字符串：

*  UNIX，Linux或Mac OSX = `\n`
 *  Windows = `\r\n`

NewLineExample.java

package com.mkyong;
    
    public class NewLineExample {
    
        public static void main(String[] args) {
    
            String original = "Hello World Java";
    
            System.out.println(original);
    
    		// add new line
            String originalNewLine = "Hello\nWorld\nJava";
    
            System.out.println(originalNewLine);
        }
    
    }

输出量

Hello World Java
    
    Hello
    World
    Java

我们还可以使用Java 1.7 [System.lineSeparator][]返回与系统有关的新行：

NewLineExample2.java

package com.mkyong;
    
    public class NewLineExample2 {
    
        public static void main(String[] args) {
    
            String original = "Hello World Java";
    
            System.out.println(original);
    
            String originalNewLine = "Hello"
                    + System.lineSeparator() + "World"
                    + System.lineSeparator() + "Java";
    
            System.out.println(originalNewLine);
        }
    
    }
