class Solution {
    public int[] dailyTemperatures(int[] temperatures) {
        int[] answer = new int[temperatures.length];
        int num = 1;
        int days = 0;

        for(int i=0;i<temperatures.length;i++){
            if(i == temperatures.length - 1)

        answer[i] = 0;

        for(days = i+1; days<temperatures.length; days++)
        num = 1;
            if(temperatures[days] > temperatures[i])
          answer[i] = num;
          num++;
        }
        return answer;
    }
}

This is my code and this is the line giving error:

if(temperatures[days] > temperatures[i])

I don't understand why it's creating error or how to fix it

you're missing {} on your inner for so it just applies to num = 1;
days = i + 1 is not checked and thus you try to get an index that's out of bounds

this is why you scope your variables properly. don't declare days so high in scope that you don't get warnings for bugs you made

declare days like you declared i

[manic trench]

i did that originally but it created an error

[remote crane]

yes, as it should

so you can get compiler errors instead of runtime errors

much easier to trace

Thank you! That did fix my error, the code isn't correct yet but now I know how to fix the rest

I'll close this now!
