藍(lán)冰飛寒

求比這個(gè)數(shù)大的最小素?cái)?shù)
沒有寫輸入函數(shù)，寫那個(gè)比較麻煩，就不寫了，


public class QiuXiaoshuSu{
    public static void main(String args[]){
    QiuXiaoshuSu z= new QiuXiaoshuSu();
    z.suanFa(11);
    }
    
    private void suanFa(int m){
        
         int j=0;
         int a=0;
         if(suShu(m)){
           m+=1;
           }
         for(int i=m;;i++){
           a=(int)(Math.sqrt((double)i));
           for( j=2;j<=a;j++){
               if(i%j==0){
              
               break;
               }
              
          
           }
             if(j>=(a+1)){
            System.out.print(i+"   ");
            break;
            }
            
         }
    
    }
    
    private boolean suShu(int m){
  boolean b=false;
      for(int i=2;i            if(m%i==0){
              b= false;
        break;
      }
        
            else
              b= true;
        }
        return b;
}
      
      }
