如何获取“JTextField 数组”的值并将其存储在 Array Integer 中？

Question

I have two arrays of JTextField and I want to store it into another array.

JTextField[] proText, atText; 


int[] burst, arrive;

I have tried the usual way of the passing the value of the array

while(true){
    if(atText[lowerBound].getText() != " " && proText[lowerBound].getText() != " "){
        bt = proText[lowerBound].getText();
        at = atText[lowerBound].getText();
        burst[lowerBound] = Integer.parseInt(bt);
        arrive[lowerBound] =Integer.parseInt(at);
        break;
    }else 
        break;
}

***the 'lowerBound' is being incremented when I click the button.

BTW this is dynamic, in which it adds another text field when I am clicking the button. The problem here is that only the last number is displayed and the rest are zero. Is there another way to get the value of a text field?

Answer 1

I read your code, the problem is simple, each time you hit one of the buttons, you re-init your arrays. Of cours the previous values will be lost.

A quick fix is to copy the values first and then store the new value in your actionPerformed method

int[] atTemp = new int[arrsize];
int[] btTemp = new int[arrsize];
for (int i = 0; i < arrsize - 1; i++) {
    atTemp[i] = at[i];
    btTemp[i] = bt[i];
}
at = atTemp;
bt = btTemp;

But if you don't know the size of your arrays then use ArrayList , then you don't have to re-init your array each time you hit the buttons.
