try{
            if(testa() == true){
            JOptionPane.showMessageDialog(null,"DeadLock!","teste",JOptionPane.INFORMATION_MESSAGE);
        }
        else{
            JOptionPane.showMessageDialog(null,"No DeadLock!", "teste", JOptionPane.INFORMATION_MESSAGE);
        }
            
        }catch(Exception e){
            System.out.println("erro");
        }
Esse é o método testa: 
public boolean testa(){
        int a = 0, x = 0, i = 0;
        String check = null, check2 = null;
       
        while(a < 7){
            check = matriz[x][0];
            while((check.equals(matriz[i][1])) || (i < 7))
                i++;
            if(check.equals(matriz[i][1])){
                check2 = matriz[i][0];
                if(check2.equals(matriz[--i][1])){
                    resultado = true;
                    return resultado;
                }
                else{
                    x++; i = x; a++;
                }
                resultado = false;
            }                
       }
        return resultado;
    }

Tenho certeza que o problema está nesse método mas não qual o problema

Ola,

Mas qual é mesmo o problema???

check = matriz[x][0];

onde vc declarou “matriz” e populou ela???

A matriz foi declarada mais acima no código, da seguinte forma:

String matriz[][] = new String[7][2];

logo após fiz a matriz é totalmente preenchida por meio de jTextFields, ex:
matriz[1][1] = jTextField1.getText();

Agora o erro dá é quando tento chamar esse método dentro de um botão, ai sempre aparece a mensagem “erro” indicando que a condição dentro do try não foi atendida, então caiu no catch.

Tá, substitui isso:

try{
            if(testa() == true){
            JOptionPane.showMessageDialog(null,"DeadLock!","teste",JOptionPane.INFORMATION_MESSAGE);
        }
        else{
            JOptionPane.showMessageDialog(null,"No DeadLock!", "teste", JOptionPane.INFORMATION_MESSAGE);
        }
           
        }catch(Exception e){
            System.out.println("erro");
        }

Por isso:

try{
            if(testa() == true){
            JOptionPane.showMessageDialog(null,"DeadLock!","teste",JOptionPane.INFORMATION_MESSAGE);
        }
        else{
            JOptionPane.showMessageDialog(null,"No DeadLock!", "teste", JOptionPane.INFORMATION_MESSAGE);
        }
           
        }catch(Exception e){
             e.printStackTrace();
        }

Ai vc pega tudo que aparecer no console (de erro) ediz para nós… pq se vc não dizer que erro que da, fica dificil heheh

Nâo, o erro a que me refiro é a mensagem que coloquei dentro da catch, lá tem um System.out.println(“erro”); essa é a mensagem de erro que eu falei, quer dizer que o que está dentro do bloco do try nunca é executado.

Tá, substitui isso:

try{
            if(testa() == true){
            JOptionPane.showMessageDialog(null,"DeadLock!","teste",JOptionPane.INFORMATION_MESSAGE);
        }
        else{
            JOptionPane.showMessageDialog(null,"No DeadLock!", "teste", JOptionPane.INFORMATION_MESSAGE);
        }
           
        }catch(Exception e){
            System.out.println("erro");
        }

Por isso:

try{
            if(testa() == true){
            JOptionPane.showMessageDialog(null,"DeadLock!","teste",JOptionPane.INFORMATION_MESSAGE);
        }
        else{
            JOptionPane.showMessageDialog(null,"No DeadLock!", "teste", JOptionPane.INFORMATION_MESSAGE);
        }
           
        }catch(Exception e){
             e.printStackTrace();
        }

Ai vc pega tudo que aparecer no console (de erro) ediz para nós… pq se vc não dizer que erro que da, fica dificil heheh

flw

Nâo, o erro a que me refiro é a mensagem que coloquei dentro da catch, lá tem um System.out.println(“erro”); essa é a mensagem de erro que eu falei, quer dizer que o que está dentro do bloco do try nunca é executado.

Meu deus cara, eu não vou ver todo seu código, postar um programa inteiro num post… não da neh. Vou falar de novo, substitui o:

System.out.println("Erro");

POR

e.printStackTrace();

se vc não entender o que eu disse, vc não sabe o que é exceção e eu aconselho vc estudar isso.

quando você tem um

try {
   //codigo
} catch(Exception e) {
  //tratamento da exceção
}

Se executar o bloco de tratamento da exceção, é claro que deu algum erro no bloco try, o fato de ter aparecido erro foi porque alguma coisa que executou no bloco try lançou uma exceção. A mensagem de erro Sysout.out.println(“erro”) é a mensagem que VOCÊ emite quando ocorre a exceção, e não a exceção que ocorreu. Quando vc executa o método printStackTrace() ele vai mostrar a pilha de execução junto com a exceção que ocorreu… e a partir dai (sabendo qual foi a exceção) que se começa a corrigir os erros.

Assim, não discute, coloca logo o e.printStackTrace(); no lugar do system.out.print(“erro”) e depois cola aqui o que aparecer…

Beleza, agora sim hehe
esse exception ai da quando vc tenta acessar uma posição invalida de um array, tipo assim:

int[] x = { 1, 2, 3, 4, 5 };
		System.out.println(x[7]);

O erro ocorre dentro do seu método testa(), mas para falar sinceramente, eu não entendi muito dele não, o que vc quer fazer ali?
eu acho que ocorre nesse ponto:

while ((check.equals(matriz[i][1])) || (i < 7))
				i++;

ali o seu while sempre vai sair com i valendo 8, ai pelo que vi sua matriz tem 7 linhas, logo vc vai tentar acessar a linha 8 e da erro
Olha esse codigo, tah igual ao seu e vai da ArrayIndexOfBound tb:

String[][] matriz = new String[7][2];
		for(int j = 0; j < 7; j++) {
			matriz[j][0] = "";
			matriz[j][1] = "";
		}
		String check = matriz[0][0];
		int i = 0;
		while ((check.equals(matriz[i][1])) || (i < 7))
			i++;

Diz o que vc quer fazer nesse método testa(), que dai posso ver se te ajudo a arrumar.

flw!
