Java StringBuilder provides two forms of indexOf() methods
- indexOf(String str) - Returns the index within this string of the first occurrence of the specified substring.
- indexOf(String str, int fromIndex) - Returns the index within this string of the first occurrence of the specified substring, starting at the specified index.
This is a simple program to demonstrate above 2 indexOf() methods with different signatures.
public class IndexOfExample { public static void main(String[] args) { StringBuilder builder = new StringBuilder("javaguides"); // method 1 int index = builder.indexOf("guides"); System.out.println(index); // method2 index = builder.indexOf("guides", 3); System.out.println(index); } }
Output:
4 4
