@@ -0,0 +1,66 @@
+Create a class Employee with the below attributes: 
+EmpId - int 
+EmpName - String 
+Dept - String
+Rating - int
+Salary - int
+
+Write getters, setters and parameterized constructor in the above mentioned attribute sequence as required.
+
+Create class Solution with the main method.
+
+Implement two static methods - findDept and findSecondHighestSalary in Solution class.
+
+findDept method: 
+-----------------------------------
+This method will take two input parameters - array of Employee objects and int parameter. The method 
+will return the dept array attribute from employee objects whose salary is matched with int parameter and rating greater than
+equal to 3. If no data found of beach objects, then the method should return null.
+
+findSecondHighestSalary method: 
+-----------------------------------
+This method will take two input parameters - array of Employee objects and string parameter. The method
+will return the second highest salary from employee objects whose dept is matched with string parameter. 
+If no data found of beach objects, then the method should return 0.
+
+Note: No two employees have same rating. All the searches should be case insensitive.
+
+These above mentioned static methods should be called from the main method.
+For findDept method - The main method should print the dept from the Employee array. If return null, then you should print 
+"No Department found".
+For findSecondHighestSalary method - The main method should print the 2nd highest salary from the Employee array with 
+the following condition. If return 0, then you should print "No data found".
