Firstly, enter the size of the array that you are concerned with. The array size, in this case, is 10. With that, you need to enter the elements of the array as well. The elements entered in this array are as follows: 1 2 3 4 4 3 2 1 1 4 You can see the frequency can be...
Java 中的数组类没有频率方法。但是我们也可以使用 Collections.frequency()来获取数组中元素的频率。 // Java program to get frequency of an element// with java.utils.Collections.frequency()importjava.util.*;publicclassFrequencyDemo{publicstaticvoidmain(String[]args){// Let us create an array of int...
If bins_array contains no values, FREQUENCY returns the number of elements in data_array. (Excel 'Analysis ToolPak' 函数的实现 FREQUENCY() 以垂直数组形式返回频率分布 语法 FREQUENCY(data_array, bins_array) data_array 必需。要计算频率的一组值的数组或引用。如果 data_array 不包含任何值,则 ...
