Question

        int[] all = {1,2,3,4,5,6,7,8,9};
        int[] db = {3,5,6,8};
        //最终结果: {0,0,3,0,5,6,0,8,0}

Answer 1

        int i,j;
        System.out.print("{");
        for (i=0; i<all.length; i++) {
         for (j=0; j<t.length; j++)
         if (all[i]==t[j]) {
         System.out.print(t[j] + (i==all.length-1?"}":","));
         break;
         } 
      if (j>=t.length) System.out.print(0 + (i==all.length-1?"}":","));
        }

Answer 2

for(int i = 0;i< all.length;i++){
            if(Arrays.binarySearch(db,all[i])<0)
                all[i] = 0;
        }

Answer 3

Arrays.fill(all,0);
        for(int i:db){all[i-1]=i;}
