        if(decimal<256){
         int binary[] = new int[8];    
         int index = 0;    
         while(decimal > 0){    
           binary[index++] = decimal%2;    
           decimal = decimal/2;    
         }    
         for(int i = index-1;i >= 0;i--){    
           System.out.print(binary[i]);    
         }

    System.out.println("Decimal of 10 is: ");  
    toBinary(256);    
    System.out.println("Decimal of 180 is: ");  
    toBinary(21);    
    System.out.println("Decimal of 31 is: ");    
    toBinary(31);
