java - Filling Hashmap without using put too much -


for context: need fill hashmap values corresponding input user gives. 1-20 in height , t in length. user can specifiy these input.

my question is, how go around filling hashmap values without repeating below 400 times?

hashmap.put(k key, v value)

the hashmap looks hashmap<string, square> square being a(empty now) class.

why not use loop e.g.

for(int i=1; i<=400; i++){   //code insert key , value    //insert hashmap   hashmap.put(k key, v value); }

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
