Problem-1:
Statement 1 is calculating number of characters stored in String phrase(which is 19) and assigning that number to integer variable phraseLength.
Statement 2 is storing the first half of the String phrase (which is "Programmi") in the String firstHalf by using substring method having index from 0 to middleIndex-1 (which is 9-1 i.e., 8).
Statement 3 is storing the second half of the String phrase (which is "ng is fun.") in the String secondHalf by using substring method having index from middleIndex to phraseLength-1.
Statement 4 is concating two strings secondHalf (which is "Programmi") and firstHalf (which is "ng is fun.") and storing concated string in String switchedPhrase (which is "ng is fun.Programmi").
Statement 5 is printing the character at the middleIndex i.e., the character at index 9 in String phrase. It outputs the following statement at the console:
Character at the middle index: n
