Java: Check whether the first two characters present at the end of a given string
Java String: Exercise-63 with Solution
Write a Java program to check whether the first two characters appear at the end of a given string.
Visual Presentation:
Sample Solution:
Java Code:
import java.util.*;
// Define a class named Main
public class Main {
// Method to check if the first two characters of a string appear at the end of the string
public boolean firstInLast(String str) {
if (str.length() < 2) // If the length of the string is less than 2, return false
return false;
else if (str.substring(0, 2).equals(str.substring(str.length() - 2, str.length())))
// If the substring of the first two characters is equal to the substring of the last two characters, return true
return true;
else
return false; // Otherwise, return false
}
// Main method to execute the program
public static void main(String[] args) {
Main m = new Main(); // Create an instance of the Main class
String str1 = "educated"; // Input string
// Display the given string and whether the first two characters appear at the end of the string using firstInLast method
System.out.println("The given strings is: " + str1);
System.out.println("The first two characters appear in the last: " + m.firstInLast(str1));
}
}
Sample Output:
The given strings is: educated The first two characters appear in the last is: true
