Is there a cleaner way of doing this if statement?

Question

if(input.charAt(i) == '0' || input.charAt(i) == '1' || input.charAt(i) == '2') {
}

Is there a way to condense this if condition, or no?

Answer 1

You could check if the character matches any index in a common String. Like,

if ("012".indexOf(input.charAt(i)) > -1) {

}
