Question

I have a String like :
“name:lala,id:1234,phone:123”
but for example I want to get only the id (the numbers) – 1234

What is the best way to do this?

Answer 1

A bit more generic than the other solutions:

    String foo = "name:lala,id:1234,phone:123";
    // get all all key/value pairs into an array
    String[] array = foo.split(",");
    // check every key/value pair if it starts with "id"
    // this will get the id even if it is at another position in the string "foo"
    for (String i: array) {
        if (i.startsWith("id:")) {
            System.out.println(i.substring(3));
        }
    }
