查找gcdjava

你好！我的代码有问题。它有一个错误，下面是图片：

这是我的密码：

private static int gcd(int a, int b, int c) {
        return gcd(gcd(a,b),c);
    }


    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

        //DecimalFormat fmt = new DecimalFormat("+##");

            inverted_x1, inverted_y1, inverted_x2, inverted_y2,

            y1 = Integer.parseInt(jTextField2.getText());
            x2 = Integer.parseInt(jTextField3.getText());

            y2Times2 = inverted_y2*2;

            RefineryUtilities.centerFrameOnScreen( chart );          
            chart.setVisible( true );             

        }catch(Exception e){
            JOptionPane.showMessageDialog(null, "Please fill necessary inputs");
        }
    }

错误显示在我的返回gcdgcda、b、c

我想得到3个数字的GCD，然后把它除以我的变量。还有别的办法吗？还是有办法解决这个错误

提前谢谢

因为gcd。。。接受3个参数

 private static int gcd(int a, int b, int c) {
            return gcd(gcd(a,b),c);
        }

作为回报，你只通过了2次。另外，对于您显示的代码，如果您传递3个参数，它将是。感谢@eis指出这一点。我忘了提到它：

gcdgcda，b，c不对，内部gcd调用只接受2个参数。此外，您的gcd方法没有任何意义。我假设这仍然是一项正在进行的工作？您只需要实现gcdinta，intb。即使在返回语句中调用，您的代码中也没有这些内容。@Diestro您可以编辑问题并将代码粘贴到其中。如您所见，注释中的代码格式不正确。请注意，此问题被编辑为不同的问题，这就是为什么一些注释和答案现在没有那么多意义的原因。。。。但是如果你通过了三次，你就会得到一个无休止的递归。我想OP需要实现两个参数的gcd。
