how to reverse a string using java

[d0ulikethat]

Use a stack to push the character onto the stack. Then pop the characters off one by one.

Or put the String into a StringBuffer which has a reverse() method

or just read the string and make a for loop, using the for loop you will iterate through the string backwards

String s =;//"User's input"

for(int i = s.length()-1; i > 0; i--) {
	System.out.print(s.charAt(i));
}

This is probably more around the level of code your looking for... Good luck, if you need things explained just ask

Good solution is there.

I tried the program, I got some errors.,I think I went wrong in declaration........Can you please send the complete program........I just want to compare and rectify my mistakes

Here is an example of how you can use StringBuffer to reverse a string

String myString = "HELLO"; //Input
StringBuffer sb = new StringBuffer(myString);
String reverse = sb.reverse().toString();
System.out.println(reverse);

@virgul: Your code does not read the last character of the string. You need to use i >= 0 instead of i > 0.

for(int i = myString.length()-1; i >= 0; i--) {

I agree with virgul.
Another thing you could do is convert the string to a character array and then use a for loop to access each element of the array and print them out.
Good Luck!
