Question

请问为什么从数据库中读取的这些数据是换行出现的呢？是哪出的问题啊？

Statement st = con.createStatement();//创建连接语句
ResultSet rs = st.executeQuery("select * from Stus"); //发送SQL命令，语句查询，得到结果集
System.out.println("学号：" +"姓名 " +"性别"+ "专业"+"年纪" );

while (rs.next()) {
String id = rs.getString("Num");
String name = rs.getString("Name");
String sex = rs.getString("Sex");
String grade = rs.getString("Specialty");
String year = rs.getString("Year");
System.out.println(id +name+sex+grade+year);
}
rs.close();
st.close();
con.close();

Answer 1

while (rs.next()) {
String id = rs.getString("Num");
String name = rs.getString("Name");
String sex = rs.getString("Sex");
String grade = rs.getString("Specialty");
String year = rs.getString("Year");
System.out.print(id +name+sex+grade+year);
System.out.print(""）;
}
