java - How can I get a Specific Item Out of a List<Map<String, Object>> -

-

when run code:

list<map<string, object>> beforedelete = query("select count(*) wp_announcement announcement_id =" + announcementid, null);  system.out.println("this count : " + beforedelete.get(0));

i result:

this count : {c1=1}

how can 1, instead of {c1=1}?

if know structure of returned map going show, value inside c1 key this:

int val = ((integer)beforedelete.get(0).get("c1")).intvalue();

add safety checks ensure result has 1 element, , initial element has key of "c1" maps java.lang.integer.

this should safe long query fixed. if query comes source outside of control, need work out other way access result.

note: assuming query makes rdbms, should parameterize query avoid injection attacks.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
