使用java倒序输出12345

int t = 12345 ;
while(t>0){
            int num = t%10;
            t /= 10 ;
            System.out.print(num);
        }

int num = 12345;
		
			num%10       					5
			num/10%10    					4
			num/100%10   num/10/10%10 		3
			num/1000%10  num/10/10/10%10     2
			num/10000%10 num/10/10/10/10%10 1
		*/
		int result=0;
		while(num>0){
			result = result*10+num%10;
			num/=10;
		}
		System.out.print(result);
