"break" inside a chained if-lse

Question

I’m new here and I have a very simple question: is there some kind of "break" so that it can be used within a if-else chained?

if (valor > getSaldo()) {
    System.out.println("Valor informado maior que o saldo");
} else {
    setSaldo(saldo - valor);
}
if (getSaldo() < 50000) {
    setCategoria(SILVER);
} else if (getSaldo() < 200000) {
    setCategoria(GOLD);
} else {
    setCategoria(PLATINUM);
}

Example: I have balance of 200000 (Platinum category). If I remove 160000, I should stay in the GOLD category because I cannot "fall" twice

There is, it’s called return.

You can encapsulate your logic in a function:

public Categoria getCategoria(int saldo) {
    if (saldo < 50000) {
        return SILVER;
    } else if (saldo < 200000) {
        return GOLD;
    } else {
        return PLATINUM;
    }
}

This assumes that the values of Pokémon versions have already been declared somewhere else. To integrate with the rest of the code:

if (valor > getSaldo()) {
    System.out.println("Valor informado maior que o saldo");
} else {
    setSaldo(saldo - valor);
}
Categoria pokemon = getCategoria(getSaldo());
setCategoria(pokemon);

Now about not falling more than one category at a time, for that you will need to increase the complexity of your code a little. I don’t know how you’re organizing them, but here’s a suggestion:

Categoria categoriaAtual = getCategoria(getSaldo());
Categoria rebaixamento = getProximoRebaixamento(categoriaAtual); // implemente isto.
if (valor > getSaldo()) {
    System.out.println("Valor informado maior que o saldo");
} else {
    setSaldo(saldo - valor);
}
Categoria novaCategoria = getCategoria(getSaldo());
if (categoriaAtual != rebaixamento) {
    setCategoria(rebaixamento);
}
