Calling arrays from other methods in a different class
- by Jake H
Hello,
I need help dealing with an array in my java program. in my first class, "test", I set 4 variables and then send them to my other class (test2).
arr[i] = new test2(id, fname, lname, case);
at that point, variables are set and then I want to return those variables. So in the test2 class, I have a method that strictly returns one of those variables
public int getId(){
return id;
}
I understand this is a little stupid, but professor gets what professor wants I guess. What I want to do now is in my main method in "test" I want to retrieve that variable and sort the array based on that int. Unfortunately, I have to create my own sort function, but I think this would work for what I want to do.
for(j = 0; j < arr.length; j++){
int indexMin =j;
for(i = j; i < arr.length;i++){
if(arr[i] < arr[indexMin]){
indexMin = i;
}
}
int tmp = arr[j];
arr[j] = arr[indexMin];
arr[indexMin] = tmp;
}
I appreciate any help anyone could provide.
Thank you
