通过textfield

Question

我需要通过文本字段获取整数。

textField_1 = new JTextField();
textField_1.addInputMethodListener(new InputMethodListener() {
    public void caretPositionChanged(InputMethodEvent e) {
        //protected void processInputMethodEvent(InputMethodEvent e){
            //InputMethodListener listener=inputMethodListener;
            //op = textField_1.getText();
            //inputnum = Integer.parseInt ( op );
            inputnum = Integer.parseInt(textField_1.getText());
            textField.setText ( String.format ( "%d + %d = ", inputnum ) );
            if(inputnum == numA ){
                score += 10;
                Correctness.setText("That's Correct!");
                correct = 1;
            }
            else{Correctness.setText("That's Incorrect!");
                } 
        }

        public void inputMethodTextChanged(InputMethodEvent arg0) {
            //inputnum = console.nextInt();     
        }
    }
}

这是这里的代码。所以我希望能够输入一个整数，然后将其设置为inputnum。我希望这里的某个人可以帮助我，因为这和大约4个小时就会到期了

Answer 1

将输入检索为字符串，然后将其转换为整数
Integer.ParseInt(String); //convert string to integer
