• String concatenation is a common operation in Java when dealing with text processing, output formatting,
and building dynamic strings for display or storage.
Output:

TASK 2: String Length

public class StringExample2 {
public static void main(String[] args) {
String str = “Java Programming”;
System.out.println(“String: “ + str);
// Get the length of the string
int length = str.length();

System.out.println(“Length of the String: “ + length);
}
}

Explanation:
• The length() method is a built-in method provided by the String class in Java.
• It returns an integer representing the number of characters in the string.
• The length includes all characters in the string, including whitespace characters such as spaces.
• In the example, the string “Java Programming” consists of 16 characters, including the space between
“Java” and “Programming”.
• The length() method is commonly used in string manipulation tasks, input validation, and text processing
to determine the size of the string dynamically at runtime.
• It’s important to note that the length of a string does not include the null character (\0) at the end of the
string, as Java strings are null-terminated.
