Java How to compare String

In Java, we use equals() to compare String.

1. equals()

1.1 To compare Strings, uses equals()

	String name = "mkyong";
	if ("mkyong".equals(name)) {
		System.out.println("Yes");

Output

Yes

1.2 The equals() is case sensitive.

	String name1 = "hello";
	String name2 = "HELLO";
	if (name1.equals(name2)) {
		System.out.println("Yes");
	} else {
		System.out.printf("NO, equals is case sensitive!");

Output

NO, equals is case sensitive!

2. equalsIgnoreCase()

To perform a case insensitive compare.

	String name1 = "hello";
	String name2 = "HELLO";
	if (name1.equalsIgnoreCase(name2)) {
		System.out.println("Yes");
	} else {
		System.out.printf("NO, equals is case sensitive!");

Output

Yes
