的确好难~~但我看明白了. 例如当你输入了15个51-60的数,10个1-10的数6个11到20的数 输出为 1-10/** 11-20/* 21-30/ 31-40/ 41-50/ 51-60/*** 61-70/ 71-80/ 81-90/ 91-.

Integer j,k,l; for(Integer i=102;i<=987;i++){ j=Integer.parseInt(i.toString().substring(0,1)); k=Integer.parseInt(i.toString().substring(1,2)); l=Integer.parseInt(i.toString().substring(2,3)); if(j*2==k&&j*3==l) System.out.println(i); }
