can you solve this problem with java

[kadriatil]

Write a short program in java (including pseudo-code) to iterate over a structure and print out the names of all users which have a score less than 70. At the end of the structure, also print out the average score of all users who scored 70 or higher. Assume a global function/procedure called print which prints all parameters passed to it and that the structure is called Structure.

Structure Prototype = [[Name1, Score1], [Name2, Score2], …]
Example Structure = [[‘Tim’, 98], [‘Tom’, 80], [‘Mike’, 50], [‘Jason’, 25]]
Example Output =
Mike
Jason
89

while I(and hopefully no one else on the site) will not do your homework for you, we can help.

step 1: read about Iterator (Java 2 Platform SE 5.0) from that site

it'll be a very simple loop depending if the list "hasNext"

thanks ice pack.. it not a home work it just a question that my father asked me. I dont know java so i cant do it. He is teasing me all the time. lol

[icepack]

well i wish my father did stuff like this!

Ideal situation for an LRStruct

I read this problem so that an actual iterator isn't needed. A simple while loop can be used.

I guess you have experience with C/C++

The following might contain error but it must be easy to fix it:

class Pair{
  private String name;
  private int score;
  Pair(String name, int score){
    this.name=name;
    this.score=score;
  }
  public int getScore(){
    return score;
  }
  public String getName(){
    return name;
  }
}

class ....{
...
  public static void main(String args[]){
    ...
    Iterable<Pair> myStructure = .... // initialize your structure.
    ...
    long sum=0;
    int count=0;
    for( Pair p : myStructure ){
       if( p.getScore() < 70 ){
           System.out.println( p.getName() );
       }
       else{
           sum+=p.getScore();
           count++;
       }
    }
     System.out.println( (double)sum/(double)count );
  }
...
}

Hope this helps...
