Simple if statement in Java [closed]

Question

How do i write an if statement in Java that displays Goodbye! if the variable word contains a letter d?

Thanks to everyone.

Answer 1

if (word.contains("d")) {
    System.out.println("Goodbye!");
}

Answer 2

Use:

if(word.indexOf("d") >= 0) {
  System.out.println("Goodbye!");
}

Answer 3

Look up the Java API docs to see what is available in the String class. There are several options including the indexOf() method that returns -1 if the given character is not in the String and an index of the character if it is found in the String.

 int ans = mystring.indexOf(mychar);

You can then use an if statement to check the ans variable.

Answer 4

if (word.contains("d")) System.out.println("Goodbye!");

Well, that was in Java!!

Answer 5

if(word.compareTo("d") == 0)
   System.out.println("Goodbye!");

or

if(word.equals("d"))
  System.out.println("Goodbye!");

That's assuming of course that word is a String and not a char.
