A class Capital has been defined to check whether a sentence has words beginning with a capital letter or not. Some of the members of the class are given below :Class nameCapitalData member/instance variables :sentto store a sentence freqstores the frequency of words beginning with a capital letterMember functions / methods :Capital( )default constructorvoid input( )to accept the sentenceboolean isCap(String w)checks and returns true if word begins with a capital letter, otherwise returns falsevoid display( )displays the sentence along with the frequency of the words beginning with a capital letterSpecify the class Capital, giving the details of the constructor( ), void input( ), boolean isCap(String) and void display( ). Define the main( ) function to create an object and call the functions accordingly to enable the task. |
