so homework question prompt user series of integers , find max , min of integer. use loop , -99 break loop.below code question is there shorter way this? feel free comment , appreciate time reading this. scanner input=new scanner(system.in); int num1,num2,max,min; system.out.print("enter number: "); num1=input.nextint(); system.out.print("enter number: "); num2=input.nextint(); max=math.max(num1,num2); min=math.min(num1,num2); while (num2!=-99){ system.out.print("enter number or -99 stop: "); num2=input.nextint(); if(num2!=-99){ max=math.max(max,num2); min=math.min(min,num2); } } system.out.println("largest is: "+max); system.out.println("smallest is: "+min); ok after working on this. did it. have small bug, don't wanna fix if anyway wants edit guest. scanner input = new scanner(system.in); int studentnum = 0; arraylist<integer> calc = new...

i have huge codebase written else not unit tested @ all. want add unit testing spring application.but code of decoupled , times code not testable. how should approach should start low level objects or high level once , can give me step step example of how write unit tests spring application. you can transform @autowired attributes @autowired constructors. check example: @component public class someclass { @autowired private somedependency somedependency; public ... dosomething(...) { ... } } can transformed to @component public class someclass { private somedependency somedependency; @autowired public someclass(somedependency somedependency) { this.somedependency = somedependency; } public ... dosomething(...) { ... } } in fact, injection method preferred since object has all dependencies needs when constructor finishes. in first approach need like: someclass someclass = new someclass(); somec...

i'm trying implement fast atan2(float) 11 bits accuracy in mantissa. atan2 implementation used image processing. might better implemented simd instruction(the impl targeting x86(with sse2) & arm(with vpfv4 neon)). for now, use chebyshev polynomial approximation( https://jp.mathworks.com/help/fixedpoint/examples/calculate-fixed-point-arctangent.html ). i'm willing implement vectorized code manually. use sse2(or later) & neon wrapper library. plan or tried these implementation option vectorized polynomial approximation chebyshev polynomial(now implemented) scalar table ( + linear interpolation) vectorized table (is possible? i'm not familiar neon, don' know instructions vgather in neon) vectorized cordic method (this may slow since require 12+ rotation iterations 11bits accuracy) else idea? the first thing want check whether compiler able vectorize atan2f (y,x) when applied array of float s. requires @ least high optimization level su...
