I need to write a java program using net beans that will make a method that will ask the user to enter names and grades.
(input will be something like: joe 94 mary 89 johnny 78)
I need to be able to put the information that the user enters into an array. Then I need to check right then if the order goes from name to grades respectively. I need to use regular expressions like using "\s+". If every odd array is not a number then i need to print out a message to the console.
I also need a method that will be able to take in the names and using string tokenizer or sort selection, be able to alphabetize the names. This is what i have so far, the grades sorting works but i am stuck there because I am supposed to let the user enter as many names and numbers as they want...

return sum/ g.length;
}
public static int[] getData (String number){
StringTokenizer token = new StringTokenizer(number);
int [] a = new int[token.countTokens()];
for (int i = 0; token.hasMoreTokens(); i++)
a = Integer.parseInt(token.nextToken());
return a;
}
public static void sortSelection(int grades[]){
for (int i = 0; i < grades.length -1; i++){
int largest = i;
for (int c = largest + 1; c < grades.length; c++)
if (grades[c]> grades[largest]) largest = c;
int temp = grades[largest];
grades[largest]= grades;
grades= temp;
}
}

int hi = g[0];

for (int a = 0; a < g.length; a++)
if (g[a]< low) low = g[a];
return low;
