generate a random number from 100 to 150, inclusive in applet

im not sure how to code the generated a random number from 100 to 150 inclusive for an applet

What have you tried? What did google tell you?

in goggle i found

int Low = 10;
int High = 100;
int R = r.nextInt(High-Low) + Low;

but r.nextInt(High-Low) + Low i know isnt applet

...what?

Please see the link in my signature on asking smart questions.

Lesson: Applets (The Java™ Tutorials > Deployment)

Code Java:

---

import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;
 
public class HelloWorld extends JApplet {
    //Called when this applet is loaded into the browser.
    public void init() {
        //Execute a job on the event-dispatching thread; creating this applet's GUI.
        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                public void run() {
                    JLabel lbl = new JLabel("Hello World");
                    add(lbl);
                }
            });
        } catch (Exception e) {
            System.err.println("createGUI didn't complete successfully");
        }
    }
}

if java.util.Random is available in applet environment then i don't see a problem. The thing is r.nextInt() where r is an instance of Random, produces negative value. So to produce a number between 100 and 150 inclusive u do is this:

Code java:

---

int a = r.nextInt() % 151 ;
a = a > 0 ? a : -1 * a ; // making it positive
if (a > 150){
    a %= 150 ; // cutting down to size
if (a < 100)
    a += 100 ;

---

if i misunderstood ur problem then sorry, very much sorry.

Ugh, seems to me like this is all he needs:

Code java:

---

int a = r.nextInt() % 51 + 100;

Why use the modulus operator at all? You're a lot closer to being correct than dumb_terminal, but I don't see a need for modulus here at all.

Besides, spoonfeeding is NOT helpful to the OP. He's probably long gone by now anyway.
