"oz"または "OZ"にelse文を入力しようとするとdoes notが進行しているように見えますが、なぜそれはわかりません。どんな助けもありがとう!感謝!!!あなたが直接Ma.contains(変換)とLa.contains(変換)を使用することができますStringBuilderのを必要としないのはなぜ私はelse文を追加するように見えません
Scanner input = new Scanner(System.in);
StringBuilder sb = new StringBuilder();
String Ma = "mass" + "MASS";
String La = "oz" + "OZ";
System.out.println("Hi, what are you trying to find?");
System.out.println("mass");
System.out.println("vol");
System.out.println("temp");
System.out.println("sphere");
System.out.println("density");
String convert = input.nextLine();
if (Ma.contains(sb.append(convert))) {
System.out.println("You are trying to convert mass.");
System.out.println("Type the unit of measurement you are trying to convert to.");
System.out.println("If you are trying to find mass type mass.");
System.out.println("pound");
System.out.println("ounce");
System.out.println("ton");
System.out.println("gram");
System.out.println("mass");
String mass = input.nextLine();
}
else if (La.contains(sb.append(convert))) {
System.out.println("34223412351Type the number of oz.");
double oz = input.nextDouble();
System.out.println(oz + " oz equal to " + oz/16 + " lb.");
System.out.println(oz + " oz equal to " + oz/32000 + " ton.");
System.out.println(oz + " oz equal to " + oz * 0.02835 + " kg.");
System.out.println(oz + " oz equal to " + oz * 28.35 + " g.");
System.out.println(oz + " oz equal to " + oz * 2835 + " cg.");
System.out.println(oz + " oz equal to " + oz * 28350 + " mg.");
}
}
}
