How to implement output line break in java

There are two methods for outputting line breaks in Java: println() method: automatic line wrapping, using System.out.println() call. "\n" escape character: Manually insert newlines, use "\n" in strings.

Outputting newlines in Java

There are two main ways to output newlines in Java:

1. println() method

• The println() method is a member of the System.out class and is used to print data and automatically wrap lines.
• Using the println() method to output newlines is very simple, just call it directly.
• Example:

System.out.println("第一行");
System.out.println("第二行");

2. "\n" escape character

• "\n" escape character represents Newline character.
• Use the "\n" escape character in a string to manually insert newlines.
• Example:

String message = "第一行\n第二行";
System.out.println(message);

Select method

• If you just want to simply output newlines, it is recommended to use the println() method.
• If you need to manually insert a newline in the string, you can use the "\n" escape character.
