An immutable class object's properties cannot be modified after initialization. The state of an immutable object remains constant throughout its lifetime. To achieve immutability, the class is designed such that its fields are initialized only once through a constructor, and no methods are provided to modify those fields. For example: String is an immutable class in Java. We can create an immutable class by following the given rules below − Make class final − class should be final so that it cannot be extended. ...

In Java, the behaviour of any variable or method is defined by the keyword used in front of its declaration. One of the non-access modifiers is static, which can be used with both methods and variables. The static methods are defined at the class level and can be accessed without creating an instance of the class, while instance methods require an object of the class for accessibility. Static methods exist as a single copy for the entire class, whereas instance methods exist as multiple copies, depending on the number of instances created for that particular class. Static methods cannot directly ... Read More

The length of the longest consecutive 1s in the binary representation of a given integer involves converting the integer to its binary form and then identifying the longest run of contiguous 1s. Here, we can represent each integer in binary as a series of 0s and 1s. Bitwise operations allow efficient bit manipulation, making it easy to count and update the longest sequence of consecutive 1s. Consider special cases such as when the integer is 0 (binary representation 0) or when it contains only 1s (e.g., for the number 7, binary 111). To understand the concept clearly, Let's go through ... Read More
