SearchName

[mia023]

I want to search an array of Students and see if the name i have is the same as the name in one of the entries of the array. This is my code:

public static Student searchLast(Stud ent st[],String last){
int N=st.length;
Student foundStudent;
st=new Student[N];
int i=0;
while(i<N&&!las t.equals(st[i].l_name)){
i++;
}
if(i==N){
foundStudent=nu ll;
}
else{
foundStudent=st[i];



}
return foundStudent;

}

Is there a question?

I have trouble with this line:
[CODE=Java]st=new Student[N];[/CODE]
What do you think its purpose is?

You are reassigning the variable "st" as it is passed when the main method called.
Stop reassigning and start checking directly with "st".

Suppose I want you to search for a cork screw (how appropriate for the time of the year ;-)
in five drawers located next to each other. What you'd probaby do is open the left
drawer and search for the item, if you haven't found it you open the next drawer.
Suppose the cork screw is in the second drawer; do you continue your search in
the third, fourth and fifth drawer? I don't think so.

kind regards,
