Can Static Variables be Called using className.variableName in Java?

Updated on 16-Mar-2024 13:43:05
Yes, in Java, static variables can be accessed using the class name followed by the variable name. Here's a brief explanation: In Java, a static variable is a class-level variable that belongs to the class rather than to instances of the class. This means that all instances of the class share the same java static variable. Static variables are declared using the `static` keyword. To access a static variable, you can use the class name followed by the dot operator and then the variable name. Her... Read Mores

What is the Number Wrapper Class and its Methods in Java?

Updated on 11-Mar-2024 10:50:06
  Introduction to `Number` Class in Java In Java, the `Number` class is an abstract superclass of numeric wrapper classes.

Count Number of Homogenous Substrings

Updated on 09-Nov-2023 17:52:13
  Introduction: Given a string s, the goal is to determine the number of homogenous substrings it contains. A string is considered homogenous if all its characters are the same. Substrings, on the other hand, are contiguous sequences of characters within a string. To handle potentially large results, the answer is returned modulo 10^9 + 7. Problem Statement: We are given a string s, and we need to count the number of homogenous substrings in it. Example 1: Input: "abbcccaa" Output: 13 Exp... Read Mores
