SimpleDateFormat df = new SimpleDateFormat("yyyy/mm/dd hh:24mi:ss");

Exception:

Exception in thread "main" java.lang.IllegalArgumentException: Illegal pattern character 'i'

Your date format pattern string contains the invalid sequence 24mi.

change to:

SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

note: the Big letter "HH" means 24 hours: e.g 23:59:00
while "hh" is 12 hours format: 11:59:00

As pointed by others, the pattern string is not correct, and can be as showed by others "yyyy/MM/dd HH:mm:ss".

Refer the java documentation for looking up the available pattern letters that could be used for formatting a date.

Snippet from the above link

G   Era designator  Text    AD
y   Year    Year    1996; 96
M   Month in year   Month   July; Jul; 07
w   Week in year    Number  27
W   Week in month   Number  2
D   Day in year     Number  189
d   Day in month    Number  10
F   Day of week in month    Number  2
E   Day in week     Text    Tuesday; Tue
a   Am/pm marker    Text    PM
H   Hour in day (0-23)  Number  0
k   Hour in day (1-24)  Number  24
K   Hour in am/pm (0-11)    Number  0
h   Hour in am/pm (1-12)    Number  12
m   Minute in hour  Number  30
s   Second in minute    Number  55

If you want hours in 24 hour format Use this

    DateFormat df=new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
    Date dd=new Date();
    System.out.println(df.format(dd));

Your pattern string is not following the java standard. This should work:

SimpleDateFormat df = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
