Mr. Vicky gave a task to his students. He gave two words, but there were some spelling mistakes found. In the first string, "!" denotes the misspelt word. The second string has the correct spelling of the first string. Create a Java application and help the students remove the "!" and replace it with the correctly spelled character.Requirements:-        Both the Strings must be of the same length. Otherwise, print "Length of the strings <String1> and <String2> does not match"-        Both the Strings must contain only alphabets and '!' symbol. Otherwise, print "<String> contains invalid symbols"-       If both the strings contain invalid symbols, print "<String1> and <String2> contains invalid symbols"-        The output must have the combined string without any symbolsAssume that space is allowed in between the words and assume that the second string always will have the correct spelt character of the misspelt first string in the respective positions.Note:In the Sample Input / Output provided, the highlighted text in bold corresponds to the input given by the user, and the rest of the text represents the output.Ensure to follow the object-oriented specifications provided in the question description.Ensure to provide the names for classes, attributes, and methods as specified in the question description.Adhere to the code template, if provided.Please do not use System.exit(0) to terminate the program. Sample Input/Output 1:Enter the first string!eadEnter the second stringrrrrread Sample Input/Output 2:Enter the first stringF!n! !utEnter the second string!i!d O!!Find OutSample Input/Output 3:Enter the first stringPo**t**nEnter the second String!!si!io!Po**t**n contains invalid symbols Sample Input/Output 4:Enter the first string!a!i!Enter the second stringV*l*dV*l*d contains invalid symbols Sample Input/Output 5:Enter the first stringpr!gra!!i!gEnter the second stringprogrammingprogramming Sample Input/Output 6:Enter the first stringC!rr!sEnter the second string!a!!yLength of the strings C!rr!s and !a!!y  does not matchSample Input/Output 7:Enter the first stringC%rr*Enter the second string&a%$yC%rr* and &a%$y contains invalid symbo
