Question

I need java equivalent of these javascript regex:

1. "abcde".search(/c/); // out: 2

2. /[^\d]/.test("123bed567"); // out: true

3. "asdgh".match(/\d/); // out: null

It’s really simple one-line solution in javascript (and in php i know too), so i expect a similar one in Java.

Answer 1

Matcher matcher = Pattern.compile("c").matcher("abcde");
System.out.println(matcher.find()?matcher.start():-1);


Matcher matcher2 = Pattern.compile("[^\\d]").matcher("123bed567");
System.out.println(matcher2.find());

Matcher matcher3 = Pattern.compile("\\d").matcher("asdgh");
System.out.println(matcher3.find()?matcher3.group():null);
