Java 尝试用循环计算BMI?
我必须做一个程序,循环五个人的BMI,我使用扫描仪输入姓名、体重和身高,但我似乎无法返回输出。我用多种方法工作 程序应该是这样的: 我所拥有的只是:Java 尝试用循环计算BMI?,java,methods,return,Java,Methods,Return,我必须做一个程序,循环五个人的BMI,我使用扫描仪输入姓名、体重和身高,但我似乎无法返回输出。我用多种方法工作 程序应该是这样的: 我所拥有的只是: public static void main(String[] args) { Scanner sc = new Scanner(System.in); int i; System.out.println("How many BMIs do you want to compute?

我该怎么做呢?用以下内容替换主管道。就您当前的代码而言,您甚至没有对定义的方法设置上限
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int i;
System.out.println("How many BMIs do you want to compute? " + 5);
for (i = 1; i <= 5; ++i) {
System.out.println("\n\nLoop " + i + " out of " + 5);
System.out.print("Client's first name: ");
String firstName = sc.next().toLowerCase();
System.out.print("Client's weight in pounds: ");
double weight = sc.nextDouble();
System.out.print("Client's height in inches: ");
double height = sc.nextDouble();
printResult(firstName, (computeBMI(wight, height))); //HERE
}
sc.close();
return;
}
你从来没有调用computeBMI或printResult。你甚至没有调用Methods。你所说的调用是什么意思?在其他方法内部?并且您正在返回for loopYes,replace return的内部;带有printResultfirstName、computeBMI重量、高度;
