Write a Java program to get a substring of a given string at two specified positions.

Visual Presentation:

Sample Solution:

Java Code:

// Define a public class named Exercise27.
public class Exercise27 {
    
    // Define the main method.
    public static void main(String[] args) {
        // Declare and initialize a string variable.
        String str = "The quick brown fox jumps over the lazy dog.";

        // Get a substring of the above string starting from
        // index 10 and ending at index 26.
        String new_str = str.substring(10, 26);

        // Display the original and the extracted substring for comparison.
        System.out.println("old = " + str);
        System.out.println("new = " + new_str);
    }
}

Sample Output:

old = The quick brown fox jumps over the lazy dog.                                                            
new = brown fox jumps
