java算法题孙浩大侠

*已知一个数组int[98],该数组里面存储了0~99共100个数字中的98个，数字不重复，

packagemyTest;importjava.util.Random;importjava.util.Arrays;publicclassDoubleBall{/**实现随机生成双色球号码:[02221316181212]红球33个球(01~33)取六蓝球16个球(01~16)取一*/publicstaticvoidmain(String[]args){int[]ary=newint[]{};Randomr=newRandom();booleansame=false;while(ary.length<6){intnum=r.nextInt(34);for(intj=0;j

packagemyTest;importjava.util.Arrays;publicclassSort{publicstaticvoidmain(String[]args){int[]ary={8,5,2,1,6,4};//bubbleSort(ary);//selectionSort(ary);insertSort(ary);System.out.println(Arrays.toString(ary));}/**冒泡排序大数向后*/publicstaticvoidbubbleSort(int[]ary){for(inti=0;iary[j+1]){intt=ary[j];ary[j]=ary[j+1];ary[j+1]=t;}}}}/**选择排序每次选出最小的数放前面*/publicstaticvoidselectionSort(int[]ary){for(inti=0;iary[j]){intt=ary[i];ary[i]=ary[j];ary[j]=t;}}}}/**插入排序*/publicstaticvoidinsertSort(int[]ary){intt,i,j;for(i=1;i=0&&ary[j]>t;j--){ary[j+1]=ary[j];}ary[j+1]=t;}}}

4.打印菱形图案

packagealgorithm50;importjava.util.Scanner;/**打印图形*/publicclassTest19{/****************************/publicstaticvoidmain(String[]args){intn;Scannerscan=newScanner(System.in);System.out.println("input:");n=scan.nextInt();for(inti=-(n-1);Math.abs(i)

packagealgorithm50;publicclassTest16{//输出9*9口诀。publicstaticvoidmain(String[]args){for(inti=1;i<10;i++){for(intj=1;j<=i;j++){System.out.print(j+"*"+i+"="+i*j+"");}System.out.println();}}}
