Infinite for loop??

So when this code is executed:

Code:Java

 
public void updatePage(int i) {
 
        Inventory page = this.getAH().get(i);
 
        System.out.println(page.getContents().length);
 
        if (!this.getItems().isEmpty()) {
            for (int index = 45; index <= 45 && index > -1; index--) {
                if (i < this.getAH().size()) {
                    System.out.println("a");
                    if (index + 1 <= 45) {
                        System.out.println("b");
                        if (index > -1) {
                            System.out.println("c");
                            if (this.getItems().contains(page.getItem(index))) {
                                System.out.println("d");
                                if (page.getItem(index++) == null
                                        || page.getItem(index++).getType() == Material.AIR) {
                                    System.out.println(index
                                            + ", "
                                            + page.getItem(index).getType()
                                                    .name());
                                    page.setItem(index + 1, page.getItem(index));
                                    page.clear(index);
                                }
                            } else {
                                page.clear(index);
                            }
                        }
                    } else {
                        if (page.getItem(index) != null
                                && page.getItem(index).getType() != Material.AIR) {
                            this.getAH().get(i++).addItem(page.getItem(index));
                        }
                    }
 

the console is spammed with
a
b
a
b
a
b
until the server crashes.

So you start at forty-five and decrease one until it's less than or equal to forty-five.

Think about your code before you write it.

 

Whatever the use of it, you check if the index (45) is smaller than or equal to 45, then decrement. Then it is still smaller and the loop goes on

 

@FisheyLP @mythbusterma Thanks guys! That fixed the initial problem but now it spams a b c d then crashes, and I have no more loops running?

 

@1Camer0471

You probably need to rewrite it, that code is quite the mess.

If I had to guess, you're modifying the loop index inside the loop and causing it to loop infinitely.

 

@mythbusterma for some reason it's not decreasing index by 1

 

@1Camer0471

Probably because I can see two separate places where you're incrementing it.
