[FIXED] How can I check if a single character appears in a string?

Issue

In Java is there a way to check the condition:

"Does this single character appear at all in string x"

without using a loop?

Solution

You can use href="http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#indexOf%28int%29" rel="noreferrer">string.indexOf('a').

If the char a is present in string :

it returns the the index of the first occurrence of the character in the character sequence represented by this object, or -1 if the character does not occur.
