1.      ArrayIndexOutOfBoundsException

2.      StringIndexOutOfBoundsException

IndexOutOfBoundsException: check the index number entered by the user is within the range of an array or string.

List<String> list1 = new ArrayList<String>(5); for(int i=0;i<10;i++){       list1.add(6,String.valueOf(i));}

ArrayIndexOutOfBoundsException: When Trying to get or put value from index which is the bigger than size of array

String[] myArray = new String[3]; myArray[4] = "ratik"; System.out.println("myArray..." + myArray[4].toString());

StringIndexOutOfBoundsException: When we try to retrieve the character at a specific index, but the specified index is much larger than the length of the string itself

String str = "Java Code Geeks!"; System.out.println("Length: " + str.length()); char ch = str.charAt(12);
