java中怎么求随机产生50个10以内的整数，输出其中重复次数最多的数？

Answer 1

public class test05 {

public static void main(String [] args) {
int array [] = new int[10];
int max = 0;
int index = 0;
for(int i=0;i<50;i++) {
int temp = (int)(Math.random()*10);
array[temp]++;
}

for(int i=0;i<array.length;i++) {
if(array[i] > max) {
max = array[i];
index = i;
}
}
System.out.println("出现次数最多的数:" +index+" "+"出现了：" +max +"次");
}
}

Answer 2

Map<Integer, Integer> map = new HashMap<Integer, Integer>();
for(int i=1;i<=50;i++){
int r = (int)(Math.random()*11);
if(map.containsKey(r))
map.put(r, map.get(r)+1);
else
map.put(r, 1);
}
Iterator<Map.Entry<Integer, Integer>> iter = map.entrySet().iterator();
Map.Entry<Integer, Integer> max = null;
while(iter.hasNext()){
Map.Entry<Integer, Integer> next = iter.next();
if(max == null || next.getValue() > max.getValue())
max = next;
}
System.out.println(max.getKey() + " " + max.getValue());
