Java - String Class, Scanner Class -

how read sentence (string) line of input, , print whether represents declarative sentence (i.e., ending in period), interrogatory (ending in question mark), or exclamation (ending in exclamation point) or not sentence (anything else)?

import java.util.*;  public class stringdemo { public static void main(string[] args){         scanner console = new scanner(system.in);          // enter string:          system.out.println("enter string: ");          string dog = console.nextline();         dog = dog.touppercase();         system.out.println(dog + " has " + dog.length() +            " letters , starts " + dog.substring(0, 1));              // enter string:         system.out.println("enter string: ");          string cat = console.nextline();         cat = cat.touppercase();         system.out.println(cat + " has " + cat.length() +            " letters , starts " + cat.substring(0, 1));         // check contents here       if(dog.equals(cat))           system.out.println("input strings matching ");       else           system.out.println("input strings not matching ");   } } 

need use .equals() method check content equality below.

import java.util.*;  public class stringdemo { public static void main(string[] args) {             scanner console = new scanner(system.in);              // enter string:              system.out.println("enter string: ");              string dog = console.nextline();             dog = dog.touppercase();             system.out.println(dog + " has " + dog.length() +                " letters , starts " + dog.substring(0, 1));                  // enter string:             system.out.println("enter string: ");              string cat = console.nextline();             cat = cat.touppercase();             system.out.println(cat + " has " + cat.length() +                " letters , starts " + cat.substring(0, 1));              // check contents here           if(dog.endswith("?"))               system.out.println("input strings ends in question mark ");      } }
