String.trim()

The trim() method in Java is used to remove the leading and trailing white spaces (or any other characters) from a string.

For example, if we have a string " Hello World! " and use the trim() method, it will return "Hello World!" with the leading and trailing white spaces removed.

Syntax:

public String trim()

Example:

String str = "   Hello World!   ";
String trimmedStr = str.trim();
System.out.println(trimmedStr); // Output: "Hello World!"
