Given a circular, integer array nums, return the next greater number for every element in nums.
Input
[9,1,2,4,3,5,8]
Output
[-1,2,3,5,4,8,9]
In other words:
9->-1
1->2
2->3
4->5
3->4
5->8
8->9
I'm very confused how to solve this problem. Please help me.

Why it's showing error, when I enter just 5 digit number in long data type?
Numbers starting with 0 are interpreted as octal numbers in Java, that are 8-based numbers. A 9 or 8 cannot appear in octal number, thus the warning.

I want to convert GBP 29.15* to just 29.15.
Can anyone please help?
I have already tried parsing to integer/float, substring etc. but getting an error.
Try this:
float f = Float.valueOf("GBP 29.15*".replaceAll("[^\\d.]+|\\.(?!\\d)", ""));
It removes all non-number characters and then finds the float value.

If I have an initialized array in Java and I want to do a method to one element in that array I would do
array[n].method();
but how do I do the same thing with an arraylist?
arraylist[n].method() gives me an error.
With Java use get method with ArrayList:
arraylist.get(n).method();
