java数组练习题带答案

for(inti=0;i<array.length;i++) { array[i]=in.nextInt(); } System.out.print("Themeanis:"+mean(array)+"\n" +"Thedeviationis:"+deviation(array));?}?publicstaticdoublemean(int[]numbers)?{ doublesum=0.0; for(inti=0;i<numbers.length;i++) { sum+=numbers[i]; } returnsum/numbers.length;?} publicstaticdoubledeviation(int[]numbers)?{ doublepowSum=0.0; for(inti=0;i<numbers.length;i++) { powSum+=Math.pow(numbers[i]-mean(numbers),2); } returnMath.sqrt(powSum/(numbers.length-1));?}}8.编写一个程序,求出整数数组中最小元素的下标。如果这样的元素个数大于1,则返回下标最小的数的下标。lassMinIndex{publicstaticvoidmain(String[]args){int[]list={1,2,4,5,10,100,2,-22};System.out.println("Theminis"+minIndex(list));}publicstaticintminIndex(int[]list){intmin=list[0];intminIndex=0;for(inti=1;i<list.length;i++)if(min>list[i]){min=list[i];minIndex=i;}returnminIndex;}
