MortgageCalculator | Mortgage Calculator - 房贷计算器

You’re probably looking for the standardInput property of the JavaExec task type. Using the following task definition, the setup worked for me (tested with Gradle 6.8.2):

In the addComma function, your replace is only going to replace the first comma it comes across. You need to have it remove every comma in the string. Try this after "txt.value =":

When your buttons are provided to the dialog in a String array then when that button is selected it is the index value to where that button name resides within the array that is returned.

Compound would return a index value of 0 from the dialog and Simple would return a index value of 1.

This error is a simple one, but I can see why it could trip you up. Basically, all of your field variables, like nameField and ageField are defined as a String at the top of your class. Change the String in this line:

The variables in your main method are local variables, so your listener won't be able to see them.

There are a lot of ways to fix this. First, you have to make the state variables (name, etc) member variables of the MortgageCalculator class, so that they'll be visible to other methods or classes. Then, give the listener code access to those variables. Some options:

• Make Next an inner class of MortgageCalculator, so that it can automatically see the member variables.
• Make MortgageCalculator implement ActionListener, and move the actionPerformed method inside the resulting class. Then, instead of writing nextButton.addActionListener(new Next());, you'd say nextButton.addActionListener(this); - but only inside a non-static method (so not main - you'd need to make main call a non-static method on an instance of MortgageCalculator).
