这是一个例子,说的是JAVA中数据数型的转换.供大家学习引
package cn.com.lwkj.erts.register;
import java.sql.Date;
public class TypeChange {
public TypeChange() {
}
//change the string type to the int type
public static int stringToInt(String intstr)
{
Integer integer;
integer = Integer.valueOf(intstr);
return integer.intValue();
}
//change int type to the string type
public static String intToString(int value)
{
Integer integer = new Integer(value);
return integer.toString();
}
//change the string type to the float type
public static float stringToFloat(String floatstr)
{
Float floatee;
floatee = Float.valueOf(floatstr);
return floatee.floatValue();
}
//change the float type to the string type
public static String floatToString(float value)
{
Float floatee = new Float(value);
return floatee.toString();
}
//change the string type to the sqlDate type
public static java.sql.Date stringToDate(String dateStr)
{
return java.sql.Date.valueOf(dateStr);
}
//change the sqlDate type to the string type
public static String dateToString(java.sql.Date datee)
{
return datee.toString();
}
public static void main(String[] args)
{
java.sql.Date day ;
day = TypeChange.stringToDate("2003-11-3");
String strday = TypeChange.dateToString(day);
System.out.println(strday);
}
}
