1,192 PointsHaving some troubles with equalsIgnoreCase.
Not sure if I am using the IgnoreCase correctly. Any insight would be greatly appreciated!
// 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("%s is equal to %s.", firstExample, secondExample);
}
if (firstExample == thirdExample.equalsIgnoreCase("hello")) {
console.printf("first and third are the same ignoring case");
}

44,806 PointsIt is possible in Java for two Strings with the same characters to have different addresses in memory. For example,
String example1 = new String("hello");
String example2 = new String("hello");
System.out.println(example1 == example2); // Prints false
To check if firstExample
and secondExample
have the same characters, the first if block would become
if (firstExample.equals(secondExample)) {
console.printf("%s is equal to %s.", firstExample, secondExample);
}
To check if firstExample
and secondExample
have the same characters ignoring case, the first line would become
if (firstExample.equalsIgnoreCase(secondExample)) {

1,192 PointsNot sure if the challenge question is posted but here it is - Add another if statement that checks if the firstExample is equal ignoring case to thirdExample. If it, is print out "first and third are the same ignoring case".
