Reverse string array

I'm trying to learn how to program and I'm wondering how to reverse my string array. Here's my code so far.

String[] words = {

"if", "you", "have", "a", "set", "of", "bad", "eggs", "it's",

"likely", "you", "get", "a", "bad", "omelet"

};

int x = 30;

int wordSpacing = 22;

void setup() {

size(200, 280);

noLoop();

}

void draw() {

for (int i = 0; i < 10; i++) {

text(words[i].toUpperCase() + ": " + words[i].length() + " letters.", 10, x);

x = x + wordSpacing;

}

You can try this Zeim,

String[] words = {

"if", "you", "have", "a", "set", "of", "bad", "eggs", "it's",

"likely", "you", "get", "a", "bad", "omelet"

};

int x = 30;

int wordSpacing = 22;

void setup() {

size(200, 24*words.length);

noLoop();

}

void draw() {

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

text(words[i].toUpperCase() + ": " + words[i].length() + " letters.", 10, x);

x = x + wordSpacing;

}

String[] words={"if", "you", "have", "a", "set", "of", "bad", "eggs", "it's","likely", "you", "get", "a", "bad", "omelet"};
for(int i=words.length-1;i>=0;i--)println(words[i].toUpperCase()+": "+words[i].length()+" letters." ); exit();

Processing comes w/ a reverse() function already:

String[] words = { 
  "if", "you", "have", "a", "set", "of", "bad", "eggs", "it's", 
  "likely", "you", "get", "a", "bad", "omelet"
};

println(reverse(words));

exit();

Anyways, here's a do-it-yourself approach:

String[] words = { 
  "if", "you", "have", "a", "set", "of", "bad", "eggs", "it's", 
  "likely", "you", "get", "a", "bad", "omelet"
};

final int len = words.length;
final int GAP = 22;

void setup() {
  size(200, 350);
  noLoop();
  background(0);

  for (int i = len; i-- != 0;
    text(words[i].toUpperCase() + ": " + words[i].length()
      + " letters.", 10, (len-i)*GAP));
}

Is it possible to loop through each character in an array and reverse them so that you get ttelemo instead of omelett for example. I tried using charAt() but that wouldn't work.

Appreciate the help by the way.

void setup(){

String hi = "hello";

println(new StringBuilder(hi).reverse().toString());

}

Thanks for the reply Hamzeen is there something I have to do to get it to work in an array though?

You can use it as follows in your case..

String[] words = {

"if", "you", "have", "a", "set", "of", "bad", "eggs", "it's",

"likely", "you", "get", "a", "bad", "omelet"

};

int x = 30;

int wordSpacing = 22;

void setup() {

size(200, 24*words.length);

noLoop();

background(0);

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

text(new StringBuilder( words[i].toUpperCase() ).reverse().toString() + ": " + words[i].length() + " letters.", 10, x);
