Aug 31, 2024 · Java provides several comparison operators that return boolean values: Example: int y = 10; boolean isXLessThanY = x < y; // true boolean isXEqualToY = x == y; // false. Logical operators allow you to combine multiple boolean expressions: Example: boolean hasScholarship = …

Mar 6, 2023 · In Java, string equals () method compares the two given strings based on the data / content of the string. If all the contents of both the strings are same then it returns true. If all characters are not matched then it returns false. Below example illustrate the use of .equals for string comparison in Java: Method 3: Using compareTo () method.

endsWith () determines whether a string contains the provided character at the end. This function compares two strings. If the strings are equal, returns true; otherwise, returns false. equalsIgnoreCase () compares two strings without taking case into account. hashCode () returns the hash code of a string.
