    Using the Java calendar class, we can add days to either the specified date or the system’s current date. The calendar class is an abstract class supported by the Java Application Programming Interface utility, which manipulates and operates with dates and times. Since it is an abstract class, you cannot employ a constructor and make an instance out of it.

    by Lucy

    Typecasting transforms one data type into another, and object typecasting includes upcasting and downcasting. The object can also be typecast in Java, just as datatypes. Additionally, there are two sorts of objects: parent and child objects. Parent to Child and Child to Parent, or Upcasting and Downcasting, are the two types of typecasting that can occur for an object.

    by Lucy

    Sorting often refers to arranging an array or collection of components in a specific order, such as ascending or descending order. Bubble Sort is the most straightforward sorting method, which repeatedly switches nearby components if they are in the wrong order. Due to its high average and worst-case time complexity, this approach is inappropriate for huge data sets.
