JAVA常用数据类型转换

?

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 typepublic static int stringToInt(String intstr){    Integer integer;    integer = Integer.valueOf(intstr);    return integer.intValue();}//change int type to the string typepublic static String intToString(int value){    Integer integer = new Integer(value);    return integer.toString();}//change the string type to the float typepublic static float stringToFloat(String floatstr){    Float floatee;    floatee = Float.valueOf(floatstr);    return floatee.floatValue();}//change the float type to the string typepublic static String floatToString(float value){    Float floatee = new Float(value);    return floatee.toString();}//change the string type to the sqlDate typepublic static java.sql.Date stringToDate(String dateStr){    return java.sql.Date.valueOf(dateStr);}//change the sqlDate type to the string typepublic 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);}}
