&& 在開關的情況下如何使用？我想將此 if-else 轉換為 switch-case。請幫幫我，我嘗試了很多選項，但沒有一個起作用。if( bpay <= 90000 && bpay >= 85000 ){System.out.println("You Job is General Manager");}if( bpay <= 84999 && bpay >= 75000 ){ System.out.println("Your Job is Manager" );}if ( bpay <= 74999 && bpay >= 65000 ){System.out.println("Your Job is Assistant Manager ");}if ( bpay <= 64999 && bpay >= 55000 ){System.out.println("Your Job is Accoutant");}if( bpay <= 54999 && bpay >= 40000 ){System.out.println("Your Job is Clerk");}if( bpay < 40000 )System.out.println("You Job is Security Incharge");

這在 Java 中是不可能的。Switch 旨在識別獨特的案例。
PS - 因為，你正在使用 android，試試 Kotlin。您可以使用 when 在 kotlin 中實現它（基本上是switch 但具有 superpowers）。例如：
when(bpay) {
in 40000..55000 -> println("Your Job is Clerk")
in 55000..65000 -> println("Your Job is Accoutant")
//Similarly for the rest
}
繁花不似錦

如前所述，這是不可能的。而是使用if-else-if：
if ( bpay <= 90000 && bpay >= 85000 ) {
System.out.println("You Job is General Manager");
} else if( bpay <= 84999 && bpay >= 75000 ) {
System.out.println("Your Job is Manager" );
} else if ( bpay <= 74999 && bpay >= 65000 ) {
System.out.println("Your Job is Assistant Manager ");
} else if ( bpay <= 64999 && bpay >= 55000 ) {
System.out.println("Your Job is Accoutant");
} else if( bpay <= 54999 && bpay >= 40000 ) {
System.out.println("Your Job is Clerk");
} else if( bpay < 40000 ) {
System.out.println("You Job is Security Incharge");
}
