Finding all uppercase letters of a string in java

Question

So I\'m trying to find all the uppercase letters in a string put in by the user but I keep getting this runtime error:

Exception in thread \"main\" java.lan         


        

Answer 1

for(int y = 0; y <= z; y++){

should be

for(int y = 0; y < z; y++){

Remember array index starts from ZERO.

String length returns

the number of 16-bit Unicode characters in the string

Because loop started from ZERO, loop should terminate at length-1.
