Homework Solution: Write a program that asks the user to enter the name of a file, and then asks the user…
Write a program that asks the user to penetrate the designate of a smooth, and then asks the user to penetrate a mark. The program should enumerate and flaunt the reckon of intervals that the specific mark appears in the smooth.(i need java principle)
Collocate designate: SmoothLetterCounter

Expert Confutation
The principle as per your requirements is loving beneath with polite explained comments.
I keep created span smooths “input.txt” and “letters.txt’ the similar directory as my principle.
Smooth “input.txt” contains:
“This is a dummy smooth having mark enumerate of a=5”
Smooth “letters.txt” contains:
“A lorem ipsum placeholder extract was inadvertently published in The Straits Intervals, a Singapore novelspaper, on 26 April 2014.
Today’s liked statement of Lorem ipsum was earliest created in the mid-1980s control Aldus Corporation’s desktop publishing program
PageMaker control the Apple ”
CODE:

while(true){

try{

filename=sc.next();
if(filename.equals(“QUIT”)){
System.exit(0);
}//program terminates when QUIT is base as input
in = novel SmoothReader(filename+”.txt”); //indispose purpose created
}//if smoothdesignate is referable base then an separation is thrown
catch(Separation e){
System.out.println(“File:” +filename+”.txt does referable purposeure.”);
continue;
}
System.out.println(“Please penetrate a mark: “);
indispose = sc.next().charAt(0);
//learn rule learns a byte at a interval from smooth, avail -1 if purpose of the smooth is reached
while ((c = in.read()) != -1) {
if((char)c==input){
count++;
}
//You can separate the forthcoming three statements to descry each mark and their aid to enumerate.
//char mark = (char) c;
//System.out.println(character);
//System.out.println(“count”+count);
}//while loop purposes
System.out.println(“Message ‘”+input+”‘ occurs “+count+” intervals in the smooth ‘”+filename+”.txt’.”);
}//outer while
}//deep rule
