Question

Let’s say I have 3 textfields on a JFrame Form. I need to get the values in the textfields and sum them up. And I want to do it with a loop. I want to make my textfields’ names txt1, txt2, and txt3. So would you please help me with the syntax?

Answer 1

Initializing an array

textField txt[3];
for(int i=0;i<3;i++)
{
    txt[i]=new textField();
}

After you’ve input in the textField,

double ans=0;
for(int i=0;i<3;i++)
{
    ans+=double.parseDouble(txt[i].paramString());
}
