17,961 PointsTo Lower Case
I"m not sure what I need to type to make it ignore case
I got the following error
JavaTester.java:80: error: no suitable method found for toLowerCase(String) } else if (firstExample == String.toLowerCase(thirdExample)){ ^ method String.toLowerCase() is not applicable (actual and formal argument lists differ in length) method String.toLowerCase(Locale) is not applicable (actual argument String cannot be converted to Locale by method invocation conversion) 1 error
// I have imported a java.io.Console for you, it is named console.
String firstExample = "hello";
String secondExample = "hello";
String thirdExample = "HELLO";
if (firstExample == secondExample){
console.printf("first is equal to second");
} elif (firstExample == String.toLowerCase(thirdExample)){
console.printf("first and third are the same ignoring case");
}

In Java for String comparison:
== tests for reference equality (are two strings the same object).
.equals() tests for value equality.
To test if two string have the same value you would use firstString.equals(secondString)
. There is also an equalsIgnoreCase()
method which may be of use for you in this challenge.
Happy coding,
