How to make the output results in Java wrap to another line?

In Java, there are the following methods to display the output results in new lines:

1. Use the '\n' escape character

The simplest way is to add the '\n' escape character where you want to break the line.

System.out.println("第一行\n第二行");

2. Use System.lineSeparator()

System.lineSeparator() method to return the newline character of the current system platform.

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

3. Use the printf() method

The printf() method can accept a format string that contains the newline escape sequence "%n".

System.out.printf("第一行%n第二行");

4. Use PrintWriter

The PrintWriter class provides an advanced writing mechanism, which provides the newline() method to wrap lines.

PrintWriter writer = new PrintWriter("output.txt");
writer.println("第一行");
writer.println("第二行");
writer.close();

5. Use the .format() method

The format() method is also a method of formatting the output string, which can contain newlines.

String str = String.format("第一行%n第二行");
System.out.println(str);

Which method to choose depends on the specific scenario and preference. The '\n' escape character and the System.lineSeparator() method are simple and commonly used choices.
