From out chart above, we see that this String begins at index 6. Here we are finding the index of the String "World". When we run our program, it prints out The index is 0 as we expect.Ĭonsider another example: public class IndexOfExample2 extends ConsoleProgram You will notice that "Hello" begins at index 0. The top row gives us the index of each character on the corresponding bottom row. Remember, a character's particular position in a string is formally known as its index. Let's take a quick look back at our chart above: 0 For example, here we are finding the index of the String "Hello" within the String "Hello World!": public class IndexOfExample extends ConsoleProgram The indexOf() method tells us the starting position, or the index, of a String within another String. ![]() For example, the three Strings "Hello world", "Hello World", and "HELLO WORLD" are all equal when we ignore case. Essentially, this means that we ignore differences in capitalization. ![]() equalsIgnoreCase() method does the same thing, but it ignores differences in case between the two strings. equals() method in the previous Strings chapter. You have already learned about using the. The equals Method versus the equalsIgnoreCase Method The right-most column gives an example of using the method. The middle column also tells us what the method does. The method signature includes the name of the method and its parameters. The middle column in the table shows us the method signature. The left-most column in the table shows us the return type of the method. In this section, we will be focusing on some of the key methods from that page which are listed in the table below: If you go to the String documentation page, you will notice that there are a lot of different methods we can use on Strings.
