if u use recursion in place of enhanced for loop in java , then u need to know the no. of elements in char array which will be done by .length method [pre-defined] //so its better to drop that idea , U can think another

convert user input to char array & then run enhanced for loop 4 it , for each iteartion increase value of a variable i by 1 //final value of i will give length of String //in java[ just thought , on assumption that we can use array & loop]
