java - How to remove a certain number from an array? -


my code far supposed 1 thing, supposed exclude "0" array , not sure how implement code , exclude number 0 when counts positive (pozitivne) numbers in code.

this code:

integer[] array = {12, 23, -22, 0, 43, 545, -4, -55, 43, 12, 0, -999, -87, 12};      int pos2 = 0, neg2 = 0;      (int : array) {         if (i >= 0) {             pos2++;         } else {             neg2++;         }     }      p1 = new int[pos2];     n1 = new int[neg2];      pos2 = 0;     neg2 = 0;      (int : array) {         if (i >= 0) {             p1[pos2] = i;             pos2++;         } else {             n1[neg2] = i;             neg2++;         }      }      system.out.print("ukupno: ");     (int : array) {         system.out.print(" " + i);     }      system.out.print("\npozitivni: ");     (int : p1) {         system.out.print(" " + i);     }      system.out.print("\nnegativni: ");     (int : n1) {         system.out.print(" " + i);     }}}

you need 2 conditions here 1 positives negatives. if remove "=" condition (i >= 0) '0' go negative's array.

integer[] array = {12, 23, -22, 0, 43, 545, -4, -55, 43, 12, 0, -999, -87, 12};  int pos2 = 0, neg2 = 0;  (int : array) {     if (i > 0) {         pos2++;     } else if(i < 0){         neg2++;     } }  p1 = new int[pos2]; n1 = new int[neg2];  pos2 = 0; neg2 = 0;  (int : array) {     if (i > 0) {         p1[pos2] = i;         pos2++;     } else if(i < 0){         n1[neg2] = i;         neg2++;     }  }  system.out.print("ukupno: "); (int : array) {     system.out.print(" " + i); }  system.out.print("\npozitivni: "); (int : p1) {     system.out.print(" " + i); }  system.out.print("\nnegativni: "); (int : n1) {     system.out.print(" " + i); }}}

same result using collections, 1 loop required filter positives , negatives.

    integer[] array = {12, 23, -22, 0, 43, 545, -4, -55, 43, 12, 0, -999, -87, 12};       list<integer> pos1 = new arraylist<>();      list<integer> neg1 = new arraylist<>();       (int : array) {          if (i > 0) {              pos1.add(i);          } else if(i < 0){              neg1.add(i);          }      }       system.out.print("ukupno: ");      (int : array) {          system.out.print(" " + i);      }       system.out.print("\npozitivni: ");      (int : pos1) {          system.out.print(" " + i);      }       system.out.print("\nnegativni: ");      (int : neg1) {          system.out.print(" " + i);      }

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...
