NumberFormat nf = new DecimalFormat("##,###.00");
String str = nf.format(0);
System.out.println(str);
如果num不为0,则结果正确。
但当num为0时,结果为.00,
如何使结果为0.00?
答案 0 :(得分:1)
请改用此数字格式:
Create table A(Id int,Name varchar(50))
create table B(Id int,A_Id int,Title varchar(50))
insert into A Values(1,'name1');
insert into A Values(2,'name2');
insert into A Values(3,'name3');
insert into A Values(4,'name4');
insert into B Values(10,1,'title1');
insert into B Values(11,1,'title5');
insert into B Values(12,2,'title2');
insert into B Values(13,2,'title6');
insert into B Values(14,3,'title3');
