60. What is the purpose of the "strictfp" keyword in Java? The "strictfp" keyword in Java is used to ensure strict adherence to the IEEE 754 standard for floating-point calculations. It ensures consistent results across different platforms by disabling some optimizations that can affect precision. 61. What is the difference between a public class and a default (package-private) class? A public class in Java can be accessed from any other class, regardless of the package they belong to. A default class, also known as a package-private class, is only accessible within the same package and cannot be accessed from outside the package. 62.
