Practice It printReverse Question?

Question

I just finished doing our PracticeIt assignment and I was stumped on the printReverse question.

After initializing phraseLength to word.length(), I put in a for loop initializing my loop control variable i to phraseLength and counted down to 0.

I continued to get an error:
threw StringIndexOutOfBoundsException:
String index out of range: 12
CodeStepByStepJavaTestHarness.printReverse(CodeStepByStepJavaTestHarness.java:4)

I don't quite understand why this doesn't work. I figured out what code works, but I just cannot figure out why this code is ending in error.

Any help is appreciated!

Answer 1

When you assign phraseLength = phrase.length(), it will store the number more then the index number in the string. Because the string index always start with 0 base, but when you count the length of the string, it will start with number 1. So, it will give you this error: StringIndexOutOfBoundsException.
