how can I get the text before and after the "-" (dash)

Question

I have a String and I want to get the words before and after the " - " (dash). How can I do that?

example: String:

"First part - Second part"

output:

first: First part
second: Second part

Answer 1

With no error-checking or safety, this could work:

String[] parts = theString.split("-");
String first = parts[0];
String second = parts[1];

Answer 2

Easy: use the String.split method.

Example :

final String s = "Before-After";
final String before = s.split("-")[0]; // "Before"
final String after = s.split("-")[1]; // "After"

Note that I'm leaving error-checking and white-space trimming up to you!

Answer 3

int indexOfDash = s.indexOf('-');
String before = s.substring(0, indexOfDash);
String after = s.substring(indexOfDash + 1);

Reading the javadoc helps finding answers to such questions.

Answer 4

    @Test
    public void testSplit() {
        String str = "First part - Second part";
        String strs[] = str.split("-");
        for (String s : strs) {
            System.out.println(s);
        }
    }

Output:

First part

Second part
