The JavaScript String indexOf function is used to find the index of a specified substring within a string. It takes one or two arguments, the first being the substring to search for and the second being an optional starting index. If the substring is found, the function returns the index of the first occurrence of the substring within the string. If the substring is not found, the function returns -1. The function is case-sensitive, meaning that it will only match substrings that have the same case as the search string. The indexOf function is commonly used in JavaScript to search for specific characters or words within a string and to manipulate strings based on their contents.

Javascript String indexOf in Java With Example Code
JavaScript String indexOf() method is used to find the index of a substring within a string. In Java, we can use the same method to find the index of a substring within a string. In this blog post, we will discuss how to use the JavaScript String indexOf() method in Java.
To use the JavaScript String indexOf() method in Java, we need to create a string object and call the indexOf() method on it. The indexOf() method takes a substring as an argument and returns the index of the first occurrence of the substring within the string. If the substring is not found, it returns -1.
Here is an example code snippet that demonstrates how to use the JavaScript String indexOf() method in Java:
String str = "Hello World";
int index = str.indexOf("World");
System.out.println("Index of World in Hello World is: " + index);
In the above code, we create a string object “Hello World” and call the indexOf() method on it with the substring “World” as an argument. The method returns the index of the first occurrence of “World” within the string, which is 6. We then print the index to the console.
In conclusion, the JavaScript String indexOf() method can be used in Java to find the index of a substring within a string. It is a useful method that can be used in various applications.
Equivalent of Javascript String indexOf in Java
In conclusion, the Java programming language provides a powerful and efficient way to search for substrings within a string using the indexOf() function. This function works similarly to the JavaScript String indexOf() function, allowing developers to easily find the position of a substring within a larger string. By using this function, Java developers can improve the performance and functionality of their applications, making it easier to manipulate and analyze text data. Whether you are a beginner or an experienced Java developer, understanding the indexOf() function is an essential skill that can help you write more efficient and effective code.
