Question

I have a test coming up in a java programming class. I need to know how to write this program, and what it looks like. It's for an intro class, so it should look rather simple, nothing too advanced. Here is what the book says:

Write a method that finds the occurrences of a specified character in the string using the following heading:

public static int count(String str, char a)

for example, count("Welcome". "e") returns 2.Write a test program that prompts the user to enter a string followed by a character and displays the number of occurrences of the character in the string.

Explanation / Answer

public static int count(String str, char a)
{
// local variable for count
int count = 0;
// loop through characters in string
for(char c : str.toCharArray())
// check if character matches, if so, update count
if(c == a)
count++;
// output
return count;
}
