inheritance - Java: do methods inherit a JRE super class, like classes inherit Object? -

-

as far know, object in java.

i looking through java jdk , experimenting creating custom jdk allows me perform more debugging operations. example, can manipulate every object changing object.java class.

my question is: methods inherit class jre well, can modify parent eg. make method save it's passed arguments?

thanks.

if want enhance debugging, can start looking @ jvmti has offer. before that, see if jdi, higher level (and therefore easier use) api built on top of jvmti suits needs.

and although you're saying doesn't sound possible in itself, similar effect can achieved instrumentation, using byte code manipulating library, bcel.

as specific example, if want record method invocations , parameters, setting breakpoint jdi , querying call stack can trick.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
