[英]How to find the lowest number in an input loop?
I have to write a code that tells the user to input 4 number (they could be decimal) and print the average and lowest of those numbers. 我必须编写一个代码,告诉用户输入4个数字(它们可以是十进制),并打印这些数字的平均值和最小值。
So far I have managed to get the average, but I'm having trouble getting the lowest of the numbers. 到目前为止,我已经设法获得了平均值,但是我很难获得最低的数字。
int iteration = 0;
float number;
float total = 0;
float average;
float lowest;
Scanner input = new Scanner(System.in);
while (iteration < 4){
System.out.println("Enter score : ");
number = input.nextFloat();
iteration++;
total += number;
}
average = total / 4;
System.out.println("The average is: " + average);
You can initialize your lowest
with value Float.MAX_VALUE
, everytime the user inputs a value, you compare your lowest with the input value and assign the new smaller value to your lowest. 您可以使用值
Float.MAX_VALUE
来初始化lowest
值,每当用户输入一个值时, Float.MAX_VALUE
lowest
值与输入值进行比较,并将新的较小值分配给最低值。
int iteration = 0;
float number;
float total = 0;
float average;
float lowest = Float.MAX_VALUE;
Scanner input = new Scanner(System.in);
while (iteration < 4){
System.out.println("Enter score : ");
number = input.nextFloat();
iteration++;
total += number;
if(number < lowest){
lowest = number;
}
}
average = total / 4;
System.out.println("The average is: " + average);
System.out.println("The minimum is: " + lowest);
Try this: 尝试这个:
float minValue = Double.MAX_VALUE;
while(...){
...
number = input.nextFloat();
minValue = Math.min(minValue, number);
...
}
Hope this will help you:). 希望这个能对您有所帮助:)。
Initially define float lowest = some big no
. 最初定义
float lowest = some big no
。 Now Every time you enter an input compare it with the lowest
. 现在,每次输入时,请与
lowest
输入进行比较。 If the input is less than lowest
assign it as lowest
, otherwise don't change lowest
. 如果输入小于
lowest
将其指定为lowest
,否则不改变lowest
。
As said by Olli Zi you can get the min value by using just a simple function Math.min().Moreover for detailed understanding i am providing the code as well. 就像Olli Zi所说的那样,您可以通过使用简单的函数Math.min()来获得最小值。此外,为了进一步理解,我也提供了代码。
int iteration = 0;
float number[]=new float[4];
float total = 0;
float average;
float lowest;
Scanner input = new Scanner(System.in);
while (iteration < 4){
System.out.println("Enter score : ");
number[iteration] = input.nextFloat();
total += number[iteration];
iteration=iteration+1;
}
average = total / 4;
System.out.println("The average is: " + average);
System.out.println(Math.min(Math.min(number[0],number[1]), Math.min(number[2],number[3])));
Hope it helps! 希望能帮助到你!
