estou fazendo um trabalho sobre threds e nao estou conseguindo fazer funcionar a barra de progresso. agradeço auxilio!!!
esta é a classe Trabalhador:package atividade;
import javax.swing.JProgressBar;
import javax.swing.JTextField;
public class Trabalhador extends Thread {
private int qtde, temp;
private double valor, total;
JProgressBar progessBar;
JTextField metaEmp, totalEmp;
public Trabalhador(){
this(0,0,0,0, null,null,null);
}
public Trabalhador(int qtde, int temp, double valor, double total,
JProgressBar progessBar, JTextField metaEmp, JTextField totalEmp) {
super();
this.qtde = qtde;
this.temp = temp;
this.valor = valor;
this.total = total;
this.progessBar = progessBar;
this.metaEmp = metaEmp;
this.totalEmp = totalEmp;
}
public void run(){
synchronized (metaEmp.getText()) {
for(int i = 0; i < qtde; i++){
try{
total += valor;
totalEmp.setText(total + "");
metaEmp.setText((Double.parseDouble(metaEmp.getText()) + valor) + "");
progessBar.setValue((int) Double.parseDouble(metaEmp.getText()));
sleep((long) (Math.random() * temp));
}catch(InterruptedException e){
}
}
}
}}
