How to count number of occurrences of pattern within a string?

Java Count 'Em Right?

• Call your project CountEmRight and create just one class, Tester. In the main method, do the following: • Create a loop that asks for String input (a sentence). • Release from the loop if the input String is “EXIT”. • So as to ignore case, convert the input String into an uppercase version of itself. • Concatenate some “harmless” String to the end of the input String. By “harmless” it is meant that it should not contain any occurrences of the delimiter expression. This is the real secret to this project… to get any occurrence of the sought after expression off the end and into the “interior” of the String. • Use the split method to produce a String array (call it sp). Then use sp.length –1 to count the number of occurrences. A typical run will appear as follows: Type in a sentence and press ENTER. His initials are SA There are 2 occurrences. Type in a sentence and press ENTER. Sad but true, their teams are better. There are 2 occurrences. Type in a sentence and press ENTER. S a sa ssa s a There are 4 occurrences. Type in a sentence and press ENTER. exit
