JES

Can you give me jsut what I have to type on JES?

Imagine that you have a list of the genders (as single characters) of all the students in your class, in order of their last name. The list will look something like "MFFMMMFFMFMMFFFM" where M is male and F is female. Write a function (below) percentageGenders(string) to accept a string that represents the genders. You are to count all of the M's and F's in the string and print out the ratio (as a decimal) of the each gender. For example, if the input string were "MFFF, " then the function should print something like, "There are 0.25 males,0.75 females."

Explanation / Answer

public void percentageGenders(String myString)

{

int male = 0, female = 0;

float mPercent=0.0, fPercent=0.0, len = 0;

for(int i = 0; i<myString.length(); i++)

{

if(myString.chatAt(i)=='M')

male++;

else if(myString.charAt(i)=='F')

female++;

len++;

}

mPercent=male/len;

fPercent=female/len;

System.out.println("There are "+mPercent+" males,"+fPercent+" females");

}
