将十进制数N转换为r进制的数（Java）代码

package src; import javax.swing.JOptionPane; public class NumberConvert { public static void main(String args[]) { LinkedStack<String> stack = new LinkedStack<String>(); //创建空栈 String inputstr; char charremainder; int sourcedecimalnumber,conversion,remainder,business; do { try { inputstr=JOptionPane.showInputDialog("请输入你需要转换的十进制数："); sourcedecimalnumber=Integer.parseInt(inputstr); break; } catch (NumberFormatException exception) { JOptionPane.showMessageDialog(null,"请输入数字（十进制数）！","提示信息",0); } }while(true); do { try { do { inputstr=JOptionPane.showInputDialog("请输入你需要转换进制（2~16之间的进制数）:"); conversion=Integer.parseInt(inputstr); if (conversion>1 && conversion<17) break; else JOptionPane.showMessageDialog(null,"请输入2~16以内的数字！","提示信息",0); }while (true); break; } catch (NumberFormatException exception) { JOptionPane.showMessageDialog(null,"请输入数字(所要转换的进制数)！","提示信息",0); } }while(true); business=sourcedecimalnumber; while(business!=0) { remainder=business%conversion; if(remainder>9) remainder+=55; else remainder+=48; charremainder=(char)remainder; char [] chararray={charremainder}; stack.push(new String(chararray)); business/=conversion; } while(!stack.isEmpty()) { System.out.print(stack.pop()); } } }
