想知道switch是怎么判断条件的吗

public class JavaSwitch {
  public static void switchMethod(int i) {
    switch(i) {
      case 1:
        break;
       case 2:
        break;
       default:
        break;
    }
  }
}

public class JavaSwitch {
  public static void switchMethod(String i) {
    switch(i) {
      case "Hello":
        break;
       case "World":
        break;
       default:
        break;
    }
  }
}

public static void switchMethod(java.lang.String);
   Code:
      0: aload_0
      1: astore_1
      2: iconst_m1
      3: istore_2
      4: aload_1
      5: invokevirtual #2                  // Method java/lang/String.`hashCode:()`I
      8: lookupswitch  { // 2
             69609650: 36
             83766130: 50
              default: 61
         }
     36: aload_1
     37: ldc           #3                  // String Hello

              default: 94
         }
     88: goto          94
     91: goto          94
     94: return
