Here is an example which accept two strings as command line arguments and perform the following operations-:
1) compare the strings
2) check if the first begins with or ends with the second string

import java.util.*;
class StringExample
{
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.print("Enter first string: ");
        String str1=input.nextLine();
        System.out.print("Enter second string: ");
        String str2=input.nextLine();
        if(str1.equals(str2)){
            System.out.println("Strings are equal!");
        }
        else{
            System.out.println("Strings are not equal!");
        }
        if(str1.startsWith(str2)){
            System.out.println("First string starts with second string");
        }
        else if(str1.endsWith(str2)){
            System.out.println("First string ends with second string");
        }
        else{
            System.out.println("First string neither starts with nor ends with second string");
        }
    }
}
