JAVA

By
                      Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. As of 2019, Java was one of the most popular programming languages in use according to GitHub,particularly for client–server web appli...

 //Assignment No.2 Set A: a) Create an employee class(id, name, deptname, salary). Define a default and parameterized constructor. Use 'this' keyword to initilize instance variabels. Keep a count of objects cretaed. Create objectes using parameterized constructor and display the objects count after each object is created.(Use static member and method). Also display the contents of each objects. Code: 👇 import java.util.*; class employee { int id; String name; String deptname; double salary; static int cnt=0; employee() { //Default Constructor } employee(int id, String name, String deptname, double salary) { this.id = id; this.name = name; this.deptname = deptname; this.salary = salary; cnt++; } static void objnum() { System.out.println("Count Of Object:"+cnt); } void display() { System.out.println(this.id+"\t"+this.name+"\t\t"+this.deptname+"\t\t"+this.salary); } public static v...
