I would like to call a method with a parameter being an object of another class, but is this object created in an earlier method?
Example:
Class A:
Public void cadastrar (Cliente cliente){
System.out.println (cliente.getNome());
}
ClassB:
Public void metodoDois (){
Cliente cliente = new Cliente();
}
ClasseA chamada = new classeA();
Chamada.cadastrar(cliente);
As it is not possible
You can change the metodoDois() and pass it by parameter to the cadastrar() method:
Class A:
Public void cadastrar (Cliente cliente){
System.out.println (cliente.getNome());
}
ClassB:
Public Cliente metodoDois() {
return new Cliente();
}
ClasseA chamada = new classeA();
Chamada.cadastrar(metodoDois());
Or create a variable outside the function metodoDois() that will be modified in the function call and then pass as a parameter of cadastrar() :
Class A:
Public void cadastrar (Cliente cliente){
System.out.println (cliente.getNome());
}
ClassB:
Cliente cliente;
Public void metodoDois() {
this.cliente = new Cliente();
}
ClasseA chamada = new classeA();
metodoDois();
Chamada.cadastrar(cliente);
