How to use strip function in Java?

1. Description

In the Java 11 release, a new strip() method has been added to remove prefix and suffix spaces from a String.

The reason for adding this method is that according to the Unicode standard, there are various space characters whose ASCII value is greater than 32 ('U 0020').

strip() can remove full-width and half-width whitespace characters before and after a string.

2. Example

public class StringStripTest {
    public static void main(String[] args) {
        String string = "    one    two    three    ";
        System.out.println("原始字符串: \"" + string+"\"");
        System.out.println("处理结果: \"" + string.strip()+"\"");
    }
}
