In this section, we will learn what the Character toLowerCase() method is and how to use in Java.

What is Java Character toLowerCase() Method?

The `toLowerCase()` method is used to return the lowercased letter of the character that we set as the argument of this method.

Java toLowerCase() Method Syntax:

static char toLowerCase(char ch)

toLowerCase() Method Parameters:

The method takes one argument, and that is the character that we want to lowercase.

toLowerCase() Method Return Value:

The return value of this method is of type `char` and that is the lower-cased letter that we’ve set as its argument.

Note: if the target character is not a letter or is already a lower-cased letter, the character itself will be returned.

    public static void main(String args[]) {

       String  s = "YOU NEVER KNOW WHAT WILL HAPPEN TOMORROW!";

       for (char c: s.toCharArray()){
           System.out.print(Character.toLowerCase(c));
       }

    }
}
