How to get Substring before Specific Character in Java ?

Answer

To get the substring before a specific character in Java, you can use the `substring` method with the index of the character.

✐ Examples

1 Substring Before '/' in "https://example.com/page"

In this example,

We create a variable named url with a value of "https://example.com/page".
We use the substring method with the index of '/' to get the substring before the specified character.
Finally, we display the substring.

Java Program

public class Main {
    public static void main(String[] args) {
        String url = "https://example.com/page";
        String substring = url.substring(0, url.indexOf('/'));
        System.out.println("Substring before '/': " + substring);
    }
}

Output

Substring before '/': https:

2 Substring Before ',' in "Hello,World"

Finally, we display the substring.

Java Program

public class Main {
    public static void main(String[] args) {
        String str = "Hello,World";
        String substring = str.substring(0, str.indexOf(','));
