Java gettext+添加数字

Question

我需要一些帮助来获取一个整数，然后在我从用户添加的内容中获取整数后，我需要向其中添加10个。感谢帮助，代码如下\

private void btnCalculateMouseClicked(java.awt.event.MouseEvent evt) 
{                                          
    Integer memoryAdd1, total, radBlue1, radWhite1, radBlack1, microsoftYes1, 
        caseA1, batteryA1, webcamA1, windows20001, windowsVista1;

    radBlack1 = 0;
    radWhite1 = 0;
    radBlue1 = 0;
    microsoftYes1 = 0;
    caseA1 = 0;
    batteryA1 = 0;
    webcamA1 = 0;
    windows20001 = 0;
    windowsVista1 = 0;
    memoryAdd1 = 0;

    if (radBlack.isSelected()) { radBlack1 = radBlack1 + 5; };

    if (radWhite.isSelected()) { radWhite1 = radWhite1 + 5; };

    if (radBlue.isSelected()) { radWhite1 = radWhite1 + 10; };

    memoryAdd.getText(Integer.toString( memoryAdd1 = memoryAdd1+10));

    if (microsoftYes.isSelected()) { microsoftYes1 = microsoftYes1 + 100; };

    if (caseA.isSelected()) { caseA1 = caseA1 + 50; };

    if (batteryA.isSelected()) { batteryA1 = batteryA1 + 30; };

    if (webcamA.isSelected()) { webcamA1 = webcamA1 + 25; };

    if (windows2000.isSelected()) { windows20001 = windows20001 + 300; };

    if (windowsVista.isSelected()) { windowsVista1 = windowsVista1 + 300; };

    total = radBlack1 + radWhite1 + radBlue1 + microsoftYes1 + caseA1 + 
        batteryA1 + webcamA1 + windows20001 + windowsVista1;

    beforeTax.setText(Integer.toString(total));

}

Answer 1

看起来只是选角的问题

    MemoryAdd1+=10 
    String str = Integer.toString( memoryAdd1)
    memoryAdd.getText(str);

顺便问一下，你的记忆是什么？是AWT文本框吗？你是在试图设定它的价值吗

Answer 2

你的问题是，一旦这个值在convert函数中，你就不能再对它进行数学运算了，因为它现在是一个字符串

试试这个

MemoryAdd1+=10

memoryAdd.getText(Integer.toString( memoryAdd1));
