42,016 Pointstask 1 states: Add an if statement that checks to see if firstExample is equal to secondExample. If it is, print out "first is equal to second".
to test if one string equals another, you use the equals method.
the documentation on the String class (specifically the equals method) states:
public boolean equals(Object anObject) Compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object.
so the equals method returns true if the String you call the method on has the same sequence as characters as the String object you pass in to it
myString.equals(someOtherString) // returns true if myString and someOtherString have the same character sequence
so to test if firstExample is equal to the secondExample you would use:
String firstExample = "hello";
String secondExample = "hello";
String thirdExample = "HELLO";
if (firstExample.equals(secondExample)) {
console.printf("first is equal to second");
}

42,016 Pointsi tried that and passed task 1 using:
// I have imported a java.io.Console for you, it is named console.
String firstExample = "hello";
String secondExample = "hello";
if (firstExample.equals(secondExample)) {
console.printf("first is equal to second");
}
String thirdExample = "HELLO";
