Convert the given string into toggle case word in Java

ToggleCase is text that is converted to mixed case version of the text using looping and if statement. A for loop is a repetition control structure which allows us to write a loop that is executed a specific number of times. The if statement allows you to control if a program enters a section of code or not based on whether a given condition is true or false. The Using ASCII Numbers convert the string into Capitalized Each Word. There are 128 standard ASCII characters, numbered from 0 to 127. Extended ASCII adds another 128 values and goes to 255.
    Example :
        Input   : Tutor Joes
        Output : tUTOR jOES

Source Code

public class toogle {
    public static void main(String args[]) {
        //Program convert the given string into tOGGLE cASE wORD
        StringBuilder a = new StringBuilder("Tutor Joes Computer Education");
        System.out.println("Original String : "+a);
 
        for (int i = 0; i < a.length(); i++) {
            if (a.charAt(i) >= 97 && a.charAt(i) <= 122) {
                int c = (int) a.charAt(i) - 32;
                a.setCharAt(i, (char) c);
            } else if (a.charAt(i) >= 65 && a.charAt(i) <= 90) {
                int c = (int) a.charAt(i) + 32;
                a.setCharAt(i, (char) c);
            }
        }
        System.out.println("tOGGLE cASE wORD Output : "+a);
    }
}

Output

Original String : Tutor Joes Computer Education
