I need a system that will execute this code every second. I've been looking for a while and still can't find any ways that work. I'm quite new to Java programming and programming for android so any help will be greatly appreciated.

```
Values n = new Values();

double num = n.getNum();
double adder = n.getAdder();
if(adder>=1) {
  num += (adder * 0.1);
}
TextView t = (TextView) findViewById(R.id.textView1);
t.setText(num + "");
n.setNum(num);

```

Also, I'm importing values from a **Values** class that looks like this,

```
package com.example.durtle02.durtle02;

public class Values {
  double num;
  double cost = 30;
  double adder;

  public double getNum() {
    return num;
  }

  public void setNum(double num) {
    this.num = num;
  }

  public double getCost() {
    return cost;
  }

  public void setCost(double cost) {
    this.cost = cost;
  }

  public double getAdder() {
    return adder;
  }

  public void setAdder(double adder) {
    this.adder = adder;
  }
}

```

**EDIT**

MainActivity.java
