I am trying to return a float array to my main class so that I can print and compare the array.
'str' that is passed into the class is declared by a global string and is taken from user input on my main class
main
public static void main (String[] args) {
Scanner sc = new Scanner(System.in);
String input = null;
System.out.print("Please enter a sentence or enter quit to end program: ");
input = sc.nextLine();
while(!input.equals("quit"))
{
System.out.println("The number of characters in the string is: " + BloorS.count(input));
System.out.println("The number of Spaces in the string is: " + Bloor_S.sCount(input));
System.out.println("The number of words in the string is: " + Bloor_S.wCount(input));
Bloor_S.print();
Bloor_S.freq(); //Change
System.out.println();
System.out.print("Please enter a sentence or enter quit to end program: ");
input = sc.nextLine();
}
sc.close();
}
class
public static float[] freq() {
char[] let = {'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'};
float [] freq = new float[26];
int a, b;
char[] char1 = str1.toUpperCase().toCharArray();
for (b = 0; b < str1.length(); b++)
{
for (a = 0; a < 26; a++)
{
if (let[a] == char1[b])
{
freq[a]++;
}
}
}
for (int f = 0; f < 26; f++)
{
freq[f] = freq[f] / strCount;
}
return freq;
}
So on the line with //Change
I want to use something along the lines of
for (int i = 0; i < 26; i++)
{
System.out.printf("%6.2f", Bloor_S.freq[i]);
System.out.printf("%3c", '|');
System.out.println();
}
So that I can print the array out 1 number at a time.
Your general idea seems fine, but you should only call Bloor_S.freq()
once and save the result into a variable. Then work with that variable. It would look something like this:
float[] freq = Bloor_S.freq();
for (int i = 0; i < 26; i++)
{
System.out.printf("%6.2f", freq[i]);
System.out.printf("%3c", '|');
System.out.println();
}
Mind you, using so many static functions is not very Java-like. The object oriented way would be to create an instance of Bloor_S
and call the (then non static) functions on that. Then either the functions could take the String
s they'll be working on as parameters or you could have a single String
as a constructor parameter.
float[] freq = Bloor_S.freq();
for (int i = 0; i < 26; i++)
{
System.out.printf("%6.2f", freq[i]);
System.out.printf("%3c", '|');
System.out.println();
}
Worked the way I want it to. Thanks.
