Need help on java H/W. Thanks

Prompt the user to input a string and then input an index. Output a string length 2 starting at the given index. If the index is too big or too small to define a string length 2, use the first 2 chars in the string. The string length output will be at least 2. Example Programs Please input a String: java Please input an index: 0 ja Please input a String: java Please input an index: 2 Va Please input a String: java Please input an index: 1 av Please input a String: java Please input an index: 3 ja
