Printing the content of void methods in java

Is there any way to print the contents of void methods just like this in java

 public boolean printings(String branchName){
 if (findBranch(branchName)!=null){
     myBranch.get(findTheBranch(branchName)).printCostumers();
     return true;
 }else{
     System.out.println("Branch does not exist");
     return false;
 }
}

Note that methods findTheBranch is working properly and the printCostumers is also a void method

private int findTheBranch(String name){
 for (int i=0;i<myBranch.size();i++){
     if (myBranch.get(i).getName().indexOf(name)>=0){
         return i;
     }
 }
 return -1;

}

public void printCostumers(){
    for(int i=0;i<myCostumer.size();i++){

        System.out.println(myCostumer.get(i).getName()+":" );
        for (int j=0; j<findTheCostumer(i).getTransaction().size();j++){
            System.out.println(findTheCostumer(i).getTransaction().get(j));
        }
    }
}

Other methods that are not mendtioned are working properly. I've tried them in other examples.

Anywhere you include

System.out.println(String x);

Java will print out x. It doesn't matter whether or not it's in a void method.

void in Java just refers to the return statement (meaning a void method doesn't return anything). It doesn't mean that the method can't output something (on the console, window, printer or somewhere else)

Also concerning your actual code: Your loop most likely doesn't print anything as it most likely is handed an empty list.
