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); }```

Answer
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.
