Question

Accepted Answer

Java is a popular programming language used for developing various applications.

Java is a high-level, object-oriented programming language.
Float is a single-precision 32-bit floating point data type, while double is a double-precision 64-bit floating point data type.
Java has three types of loops: for, while, and do-while.
While loop checks the condition before executing the code block, whereas do-while loop executes the code block first and then checks the condition.
For loop is used when the number of iterations is known, while for-each loop is used to iterate over elements of an array or collection.
A class method is a method that is associated with a class rather than with an instance of the class.
Encapsulation is the concept of bundling the data (attributes) and methods (functions) that operate on the data into a single unit.
Static keyword is used to create class-level variables and methods.
Access refers to the visibility of a class, method, or variable to other classes.
Math.random() is a method in Java that returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0.
