+create a class Antenna with below attributes.
+
+antennaid-int
+
+antennaName-String
+
+projectLead-String
+
+antennaVSWR-double
+
+the above attribute should be private ,write getter and setter and parametrized constructor as well.
+
+create class MyClass with main method.
+implement two static methods searchAntennaByName and sortAntennaByVSWR in MyClass class.
+
+
+searchAntennaByName :
+---------------------------------------
+This method will take an array of Antenna objects and the string value as input parameter.The method will find out Antenna name(String parameterpassed).
+It will return Antennaid if found.if there is no Antenna that matches then the method will return zero.
+The main method should print the antennaid,if the returned value is not 0.if the returned value is 0 then print,"There is no antenna with the given parameter".
+
+
+sortAntennaByVSWR:
+--------------------------------------
+This method will take an array of Antenna Objects and a double value as input.
+This method will return an array of Antenna objects sorted in ascending orderof their antennaVSWR, which is less than VSWR(double value passed).       
+
+The main method should print name of the project leads from the returned array if the returned value is not null.if the returned value is null then main method 
+should print "No Antenna found";
