In the previous lesson, we looked at how we can convert string type values into uppercase or lowercase. In this lesson, we shall learn how we can compare values of string type using inbuilt methods provided in Java programming language. When we compare string values in Java, all Java do is to compare the Unicode hexadecimal values of the passed string values. We are going to use an inbuilt Java method called compareTo to compare two string values and determine if they are equal or not. Create another class in java, call it CompareStrings and write the following code and run. You can go ahead and use the defined variables or you can define your own string variables. Later, you can interchange and modify these string variables and compare again to see how java compare mixed cases strings i. We have then used the method compareTo to compare the two strings and store the returned value in another variable named myresult. If the value returned is a zero then the two strings are equal i. Any other value returned will mean the strings are not the same. You will see that this time you will get a different output.

All original content on these pages is fingerprinted and certified by Digiprove. When working with custom types, or trying to compare objects that aren't directly comparable, we need to make use of a comparison strategy. Nevertheless, Java 8 designers have gone ahead and annotated the Comparator class interface FunctionalInterface to enforce its role as a Functional Interface.
