Issue
I created a graphical interface in a small program in Java. When you create the fields in the graphical interface, you have automatically created the actionPerformed(java.awt.event.ActionEvent evt) methods, which are automatically private methods. I created a JTextField to receive what the user types. Then I created a string variable, such as: String inputfieldinstring = inputtext.gettext().Tostring(); Then I turned into an integer variable: int inputValueInteger = Integer.parseInt(inputfieldinstring);
How to transfer the inputValueInInteger variable, which is within the private inputTextActionPerformed (java.awt.event.aVTEvent EvT) method for another method to process data processing?
Below, I want to take the variable called inputValueInInteger that is inside the ActionPerformed(java.awt.event.ActionEvent evt), which is a private method, and transfer to other method to do the processing. How do you do this?
private void inputTextActionPerformed(java.awt.event.ActionEvent evt) {
String inputFieldInString = inputText.getText().toString();
inputValueInInteger = Integer.parseInt(inputFieldInString);
}```
Solution
you can declare it as a static variable:
public class MyFirstClass {
private static Integer inputValueInteger;
public Integer getInputValueInteger() {
return inputValueInteger;
}
private void inputTextActionPerformed(java.awt.event.ActionEvent evt) {
String inputFieldInString = inputText.getText().toString();
inputValueInInteger = Integer.parseInt(inputFieldInString);
}
}
===========================
public class AnotherClass {
public void somethingmethod(String something) {
Integer inputValueInInteger = MyFirstClass.getInputValueInteger();
// Do your other thing in the method
}
Alternatively you can declare a static storage
public class Storage {
private static Map<String, Integer> storageRepresentative = new ArrayList<>();
public getStoreValue(String key) {
return storageRepresentative.get(key);
}
public void storeValue(String key, Integer number) {
storageRepresentative.put(key, number);
}
===============
In your MyFirstClass
public class MyFirstClass {
private static Integer inputValueInteger;
public Integer getInputValueInteger() {
return inputValueInteger;
}
private void inputTextActionPerformed(java.awt.event.ActionEvent evt) {
String inputFieldInString = inputText.getText().toString();
inputValueInteger = Integer.parseInt(inputFieldInString);
//Store your values here
Storage.storeValue("current", inputValueInteger);
}
}
=====================
public class AnotherClass {
public void somethingmethod(String something) {
Integer inputValueInInteger = Storage.getStoreValue("current");
// Do your other thing in the method
}
It depends on your needs.
