Question

Consider the following code segment.

String a = ""; a += "0"; if (a == "0") { System.out.println("a is 0!"); } else if (a == "1") { System.out.println("a is 1!"); } else if (a == "a") { System.out.println("a is a!"); } else { System.out.println("a is something else!"); }

Which of the following statements about the code segment is true?

It produced "a is 0!" as output

It produced "a is 1!" as output

It produced "a is a!" as output

It produced "a is something else!" as output

It results in an error because the == operation can not be used with Strings

Answer 1

It will results in an error because == cannot be used with strings.

With strings we use .equals().
