exception in thread "main" java.lang.indexoutofboundsexception: index 1 out of bounds for length 1
0 means you are trying to access index 0 which is invalid, which in turn means the array is empty.
String[] names = new String[0]; // thats the problem
String[] names = new String[somelength];//this is true usagejava.lang.indexoutofboundsexception: index: 0, size: 0
The problem is that you are using set method to update element at index 0
set(index,value) method needs an element to present at that index
but you haven't added any element at that position in medium arraylist before that .
So you need to first add an element at index 0 thereafter only you can update it with set methodCopyright © 2021 Codeinu
