+Create a class Institution with below attributes:
+
+institutionId - int
+institutionName - String
+noOfStudentsPlaced - int
+noOfStudentsCleared- int
+location - String
+grade - String
+
+Write getters, setters for the above attributes.
+Create constructor which takes parameter in the above sequence except grade.
+
+Create class Solution with main method.
+Implement two static methods - FindNumClearancedByLoc and UpdateInstitutionGrade in Solution class.
+
+FindNumClearancedByLoc method:
+----------------------------------------------
+This method will take two input parameters - array of Institution objects and string parameter location.
+The method will return the sum of the noOfStudentsCleared attribute from institution objects for the location passed as 
+parameter. If no institution with the given location is present in the array of institution objects, then the method 
+should return 0.
+
+UpdateInstitutionGrade method:
+-----------------------------------------------
+This method will take a String parameter institutionName, along with the array of Institution objects.
+The method will return the institution object, if the input String parameter matches with the institutionName attribute of the 
+institution object. Before returning the object, the grade should be arrived based on the rating calculation mentioned below. 
+This grade value should be assigned to the object.If any of the above conditions are not met, then the method should return 
+null.
+
+* The grade attribute should be calculated as follows:
+
+Rating=(noOfStudentsPlaced * 100)/noOfStudentsCleared
+If the rating >= 80 , then grade should be 'A'.
+Else, then grade should be 'B'
+
+**Note:**
+--------------------------------------------
+No institution object would have the same value for institutionName attribute.
+All institution object would have the noOfStudentsPlaced value lesser than noOfStudentsCleared value.
+All the searches should be case insensitive.
+
+The above mentioned static methods should be called from the main method.
+
+For FindNumClearancedByLoc method - The main method should print the noOfClearance as it is, if the returned value is 
+greater than 0, or it should print "There are no cleared students in this particular location".
+
+For UpdateInstitutionGrade method - The main method should print the institutionName and grade of the returned Institution 
+object. The instituationName and grade should be concatinated with :: while printing. eg:- TCS::A, where TCS is the 
+institution name and A is the grade.
+If the returned value is nullthen it should print "No Institute is available with the specified name".
+
+Before calling these static methods in main, use Scanner object to read the values of four Phone objects referring attributes 
+in the above mentioned attribute sequence (except grade attribute). Next, read the value for location and institutionName.
