Java String : compareToIgnoreCase() Method

compareToIgnoreCase() method - Compare two strings lexicographically without considering case

The compareToIgnoreCase() method is used to compare two strings lexicographically, ignoring case differences.

Note: This method does not take locale into account, and will result in an unsatisfactory ordering for certain locales. The java.text package provides collators to allow locale-sensitive ordering.

Java Platform: Java SE 8 and above.

Syntax compareToIgnoreCase() method

compareToIgnoreCase(String str)

Parameters compareToIgnoreCase() method

Return Value compareToIgnoreCase() method

• A negative integer, zero, or a positive integer as the specified String is greater than, equal to, or less than this String, ignoring case considerations.

Return Value Type: int

Example: Java String compareToIgnoreCase() Method

The following example shows the usage of java String() method.

public class Exercise {

public static void main(String[] args)
    {
        System.out.println();
        String str1 = "This is Python exercise 1";
        String str2 = "This is Ruby Exercise 1";

System.out.println("String 1: " + str1);
System.out.println("String 2: " + str2); 

        // Compare the two strings.
int result = str1.compareToIgnoreCase(str2);

        // Display the results of the comparison.
if (result < 0)
        {
System.out.println("\"" + str1 + "\"" +
" is less than " +
                "\"" + str2 + "\"");
        }
else if (result == 0)
        {
System.out.println("\"" + str1 + "\"" +
" is equal to " +
                "\"" + str2 + "\"");
        }
else // if (result > 0)
        {
System.out.println("\"" + str1 + "\"" +
" is greater than " +
                "\"" + str2 + "\"");
        }
    }
}

Output:

String 1: This is Python exercise 1                    
String 2: This is Ruby Exercise 1                      
"This is Python exercise 1" is less than "This is Ruby 
Exercise 1"
