Question

我需要一些帮助gettext一个整数然后在我从用户添加的整数中得到整数后，我需要添加10来感谢下面的代码的帮助; \

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

它看起来只是铸造问题..



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

顺便问一下你的记忆是什么？这是AWT文本框？你试图设定价值吗？

Answer 2

你的问题是，一旦值在转换函数中，你就不能再用它做数学，因为它现在是一个字符串。

试试这个

MemoryAdd1+=10

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

Java gettext +添加一个数字
