How do I concatenate all my arrays into a single long array? concat does not seem to be working as the error appears: The function “concat()” expects parameters like: “concat(int[],int[])”

void setup() {

  
  
  println("chromosome0");
  determineSymmetry(); 
  int [] chromosome0 = tempChromosome.clone();
  printArray(chromosome0);

  println("chromosome1");  
  determineSymmetry();
  int [] chromosome1 = tempChromosome.clone();
  printArray(chromosome1);  
  
  println("chromosome2");  
  determineSymmetry(); 
  int [] chromosome2 = tempChromosome.clone();
  printArray(chromosome2);  
  
  println("chromosome3");  
  determineSymmetry();
  int [] chromosome3 = tempChromosome.clone();
  printArray(chromosome3);  

  println("chromosome4");
  determineSymmetry();
  int [] chromosome4 = tempChromosome.clone();
  printArray(chromosome4);  
  
  println("chromosome5");
  determineSymmetry();
  int [] chromosome5 = tempChromosome.clone();
  printArray(chromosome5);
  
int[] genotype = concat(chromosome0, chromosome1, chromosome2, chromosome3, chromosome4, chromosome5);


 
 println("genotype");
 printArray(genotype);
}
