java equals ignore case

In Java, you can use the equalsIgnoreCase() method of the String class to compare the contents of two String objects for equality, ignoring case. The equalsIgnoreCase() method is similar to the equals() method, but it compares the contents of the String objects in a case-insensitive manner.

Here's an example of how to use the equalsIgnoreCase() method to compare two String objects in Java:

public class Main {
    public static void main(String[] args) {
        String str1 = "Hello";
        String str2 = "hello";
        String str3 = "HELLO";

        System.out.println(str1.equalsIgnoreCase(str2));  // true
        System.out.println(str1.equalsIgnoreCase(str3));  // true
    }
}

In this example, three String objects are created: str1, str2, and str3. str1 and str2 are initialized with the same string literal in different cases, and str3 is initialized with a string literal in uppercase.

The equalsIgnoreCase() method is called on str1 and passed str2 and str3 as arguments. The equalsIgnoreCase() method compares the contents of the String objects in a case-insensitive manner and returns true if they are equal, and false otherwise.

In this example, the equalsIgnoreCase() method returns true for both comparisons because the contents of the String objects are equal, ignoring case.

You can use the equalsIgnoreCase() method to compare the contents of two String objects in a case-insensitive manner in Java. Just call the equalsIgnoreCase() method on one of the String objects and pass the other String object as an argument.
