将设置有小时和分钟的字符串，转为今天的几时几分的时间

package com.liyh.test;

import java.util.Calendar;
import java.util.Date;
import java.util.StringTokenizer;

public class Test {
public static void main(String[] args) {
slip("12:00");
}

public static Date slip(String time){
StringTokenizer st = new StringTokenizer(time, ":");
int i=0,count = st.countTokens();
String[] array = new String[count];
while (st.hasMoreElements()) {
array[i++] = st.nextToken();
}
int hour=0,minute=0;
for(int j=0;j<array.length;j++){
if(j==0){
hour=Integer.parseInt(array[j]);
// System.out.println("hour : "+array[j]);
}
if(j==1){
minute=Integer.parseInt(array[j]);
//System.out.println("minuse : " +array[j]);
}
}
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR,hour-12);
cal.set(Calendar.MINUTE,minute);
cal.set(Calendar.SECOND,0);
Date date = cal.getTime();
return date;
}

}
修改版：
package com.liyh.test;

import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.List;
import java.util.StringTokenizer;

public class Test {
public static void main(String[] args) {
System.out.println(slip("15:00"));
}

public static Date slip(String time){
StringTokenizer st = new StringTokenizer(time, ":");
List<String> list = new ArrayList<String>();
while (st.hasMoreElements()) {
list.add(st.nextToken());
}
int hour=0,minute=0;
hour = Integer.parseInt(list.get(0));
minute=Integer.parseInt(list.get(1));
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR,hour-12);
cal.set(Calendar.MINUTE,minute);
cal.set(Calendar.SECOND,0);
Date date = cal.getTime();
return date;
}

}
