Objetos.....pegar valor de uma variavel em outra classe.....ajuda

leonardocp · Novembro 25, 2009, 7:59pm

como faço para pegar o valor da variavel “totalDeRetiradas;” e colocar em outra classe dando o valor da mesma a uma jLabel…

public double somaRetiradas() { double totalDeRetiradas=0; for(int i=0; i < jTable_transacoes.getRowCount(); i++) { totalDeRetiradas = totalDeRetiradas+ Double.parseDouble(jTable_transacoes.getValueAt(i,2).toString()); } jTextField2.setText("R$ "+totalDeRetiradas); return totalDeRetiradas; }

Crie um método que receba um double como argumento na outra classe, e passe essa variável totalDeRetirada como argumento e depois é só setar no JTextField.

Atc,
Fernando.
