我正在尝试编译,我收到此错误:

enigma/Rotor.java:30: incompatible types found : java.lang.String required: int     switch(name){
1 error

为什么我收到此错误？我如何解决它？它在包中,我似乎无法弄明白.这是代码:

String label;

Rotor(String name){

      conversion_chart = B;
      break;
    case "C":
      conversion_chart = C;
      break;
    case "I":
      conversion_chart=I;
      notch = NOTCH[0];
      break;
    case "II":
      conversion_chart=II;
      notch = NOTCH[1];
      break;
    case "III":
      conversion_chart=III;
      notch = NOTCH[2];
      break;
    case "IV":
      conversion_chart=IV;
      notch = NOTCH[3];
      break;
    case "V":
      conversion_chart=V;
      notch = NOTCH[4];
      break;
    case "VI":
      conversion_chart=VI;
      notch = NOTCH[5];
      break;
    case "VII":
      notch = NOTCH[6];
      conversion_chart=VII;
      break; …
