public class MyClass { public static void main(String args[]) { // various string manipulation methods in Java } }
Understand the Problem
The question presents a Java program that demonstrates various string manipulation methods such as charAt, concat, contains, and many others. It shows how to use these methods and outputs their results to the console.
Answer
Use methods like `length()`, `substring()`, `indexOf()`, `toLowerCase()`, `toUpperCase()`, `charAt()`, `concat()`, `replace()`, `trim()`, `split()`.
You can use Java string manipulation methods such as length(), substring(int beginIndex, int endIndex), indexOf(String str), toLowerCase(), toUpperCase(), charAt(int index), concat(String str), replace(char oldChar, char newChar), trim(), and split(String regex).
Answer for screen readers
You can use Java string manipulation methods such as length(), substring(int beginIndex, int endIndex), indexOf(String str), toLowerCase(), toUpperCase(), charAt(int index), concat(String str), replace(char oldChar, char newChar), trim(), and split(String regex).
More Information
Java provides a rich set of methods to manipulate strings efficiently. Understanding these methods is essential for text processing or handling user inputs.
Tips
A common mistake is to assume strings are mutable in Java. Remember, String is immutable. To make multiple modifications, consider using StringBuilder or StringBuffer.
