When the input contains words both having different frequencies and the same frequency cnt[12] = "hello aloha hi hi hello"; ept[12].put("hello", 2); ept[12].put("hi", 2); ept[12].put("aloha", 1); // Case 13: When the input contains words concatenated using hyphens cnt[13]...
Here is the Java program to find the duplicate word which has occurred a maximum number of times in a file. You can also print the frequency of words from highest to lowest because you have the Map, which contains the word and their count in sorted order. All you need to do isiterate...
在这个例子中,使用Collections.frequency()方法可以简单地计算目标元素在列表中出现的频率。 3. 计数器的应用 在更复杂的场景中,我们可能需要创建一个计数器来统计不同元素的出现次数。例如,使用HashMap来记录每个元素的计数: importjava.util.HashMap;publicclassCountUsingMap{publicstaticvoidmain(String[]args){Strin...
