How to reverse a string in java ?

>> In Java we can reverse a string using for loop, string buffer, string builder,....

public class reverse {
    public static void main(String[] args) {

    String str = "WELCOME";

    char[] carray = str.toCharArray();
    String rev = "";

    for (int i = 0; i <= carray.length - 1; i++) {
        rev = rev + str.charAt(carray.length - i - 1);
    }
    System.out.println("reverse string using for loop=" + rev);
    String reve = "";
    for (int i = carray.length - 1; i >= 0; i--) {
        reve = reve + str.charAt(i);
    }
    System.out.println("<<------------------------------------------>>");
    System.out.println("reverse string using for loop=" + reve);
    
    System.out.println("<<------------------------------------------>>");
    StringBuilder sb = new StringBuilder(str);
    System.out.println("reverse string using StringBuilder reverse method=" + sb.reverse());
    
    System.out.println("<<------------------------------------------>>");
    StringBuffer sber = new StringBuffer(str);
    System.out.println("reverse string using StringBuffer reverse method=" + sber.reverse());
    }
}
