Expert Solution & Answer
Chapter 4.3, Problem 22SCP
Explanation of Solution
Given code snippet:
//declare and initialize the variable
int count=0;
//loop to check the number of occurrences
for(int i=0; i<s.length(); i++)
//condition initialized to check whether the letter is occurring multiple times
if(s.charAt(i).toLowerCase=='e') {
//increment the value
count++;
}
}
Error in the above code:
- In this case, the “toLowerCase” method cannot be called on a char value, which is what is returned by “charAt” method.
- It can be rectified by calling the “Character.toLowerCase” method on the characters of the string.
- The rectified code is given below:
Corrected code:
//declare and initialize the variable
int count=0;
//loop to check the number of occurrences
for(int i=0; i<s...
