its not working...please assist me because i dont know what to do next...thanks

It wouldn't work because you did not write it in Java.
If/else should look something like

if(i < 1){
//do something
}
else if(i > 1 && i < 5){
//do something
}
else{
//do something
}

You better find all notes your instructor gave you and start reading as you are seriously behind.

till the same but its till not working.....please help me by running it on your laptop to check if it running......thanks

Till you provide some proper code nobody will pay any attention to your pleads & cry

import javax.swing.JOptionPane;



   public class consignment {

    public static void main(String[] args) {
    int dimension;
    int weight;
    int price per parcel;
    int total weight;
    int  price consigment;
  String  number of parcels;

    numStr=JOptionPane.showInputDialog("enter prices");
    //convert from  String to int
    num = Integer.parseInt(numStr);

       if (num == 2kg)
    //do something
     JOptionPane.showMessageDialog(null,"the price is £7.50");

     else if (num == 4kg)
    //do something
     JOptionPane.showMessageDialog(null,"the price is £8.00");
     else  if (num == 6kg)
    //do something
     JOptionPane.showMessageDialog(null,"the price is £8.55");
     else if (num == 8kg)
    //do something
     JOptionPane.showMessageDialog(null,"the price is £9.10");
     else  if (num == 10kg)
    //do something
     JOptionPane.showMessageDialog(null,"the price is £9.70");
    else if (num == 12kg)
    //do something
     JOptionPane.showMessageDialog(null,"the price is £10.35");

      else ((num == 2kg && num == 30))
    //do something
     JOptionPane.showMessageDialog(null,"the price is £0.90");

     system.exit();
   }

   }

its still giving me errors

Yes it wouldn't work because you ignored brackets that are supposed to be around content that will be executed if condition is true.
Time to start reading Java Tutorials

PS: Your assignment says "up to" meaning example from 0-2kg, 2-4kg so there wouldn't be "=="

import javax.swing.JOptionPane;



    public class consignment {

    public static void main(String[] args) {
    int dimension;
    int weight;
    int price per parcel;
    int total weight;
    int price consigment;
    String number of parcels;

    numStr=JOptionPane.showInputDialog("enter prices");
    //convert from String to int
    num = Integer.parseInt(numStr);

    if (num 0-2kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £7.50");
    }
    else if (num 2-4kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £8.00");
    }
     else if (num 4-6kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £8.55");
     }
     else if (num 6- 8kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £9.10");
    }
    else if (num 8-10kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £9.70");
    }
     else if (num 10-12kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £10.35");
    }
    else (num  2kg-30kg){
    //do something
    JOptionPane.showMessageDialog(null,"the price is £0.90");

    system.exit();
    }

    }

still nt workin..what wrong

1) When you post any code use code tags [code] YOUR CODE HERE [/code]
2) Do not expect to be just spoon-fed, investigating errors and try to understand what is compiler complaining about. It is you who is suppose to learn something, not us.
3) I did not mean that you put inside if/else directly 0-2kg. This is basic programming stuff that you should understand before you attempt to solve it. God damn it, even my neighbour 10 years old son can do better then this...
4) Either find notes from your class or start reading that Java tutorial(already linked in my previous reply on other thread from you)
5) Till you start showing some work on this I do strongly discourage anyone giving you any code

okay have heard you.....i will do it myself..dnt nid ur help animore

you will need to use some other operators the ==.

Google Java operators
