How to find the position of the first occurrence of a substring in a string with Java

Answer 1

public class FindSubstring {
    public static void main(String[] args) {
        String str = "I bought running shoes, but they started running alone, now we are both happy";
        String substring = "running";

        // Find the position of the first occurrence of a substring
        int position = str.indexOf(substring);

        if (position != -1) {
            System.out.println("The first occurrence of \"" + substring + "\" is at position: " + position);
        } else {
            System.out.println("Substring not found!");
        }
    }
