Question
Fix the Java code, make sure:
Leave comments as explaination how the code work.
The program has no console input, so it doesn't use Scanner.
Don't use any class-level (static) variables. Every variable should be declared inside of a method.
Code:
public class Main
{
publicstaticvoid main(String[] args){
//check if length of the command line arguments is 0
//then display the message how to use program
if(args.length==0){
System.out.println("usage : java Main 5 4 2 8");
System.out.println("To average the numbers 5,4, 2 and 8");
}
else{
System.out.println("Here is you areray of numbers:");
//call displayarray function
displayarray(args);
//display the average value
System.out.println("and their average is :"+
getaverage(args));
}
}
/*The function1, getaverage takes a string array as input array
* and then calculate the average of array values and
* return the array average */
privatestaticdouble getaverage(String[] args){
double total=0;
for (int i =0; i < args.length; i++)
{
total=total+Double.parseDouble(args[i]);
}
return (total/args.length);
}
/*Function2, displayarray takes string array and prints the
* array values on console window*/
privatestaticvoid displayarray(String[] args) {
System.out.print(args[0]+",");
for (int i =1; i < args.length-1; i++) {
System.out.print(args[i]+",");
}
System.out.print(args[args.length-1]);
System.out.println();
}
}//end of the Main class
Sample output in the picture
Transcribed Image Text:as shown below. Here is some sample output:
> java -classpath .:/run_dir/junit-4.12.jar:target/dependency/" Main
usage: java Main 5 4 2 8
To average the numbers 5, 4, 2 and 8
> java Main 1.5 2 2.5 43.222 3
Here is your array of numbers:
1.5, 2.0, 2.5, 43.222, 3.0
and their average is: 10.4444
> java Main 1 2 3 4
Here is your array of numbers:
1.0, 2.0, 3.0, 4.0
and their average is: 2.5
