The problem is that you keep searching until the end of the list. So, even if you found a matching item, the next elements may be different from the one you seek, and therefore the else would be true.
\nWhat you need to do, is display the “not found” message only if no matching element was found:
\nUse a boolean flag found like this: <\/p>\n

    int opcao = Integer.parseInt(JOptionPane.showInputDialog(\"Digite o ID para a busca\"));\n        boolean found = false;\n\n        \/\/'for' para percorrer o vetor\n        for (Produto objProduto : vetorProdutos2) {\n         \/\/if para verificar se o ID digitado para busca cont\u00e9m no vetor\n         if (objProduto.getId() == opcao) {\n                     JOptionPane.showMessageDialog(null,\n      \"\\nID: \" + objProduto.getId()+\"\\nDescri\u00e7\u00e3o: \" + objProduto.getDescricao()\n                                                    + \"\\nEstoque: \" + objProduto.getEstoque() + \"\\nPre\u00e7o: \"\n                                                    + objProduto.getPre\u00e7o() + \"\\nStatus: \" + objProduto.getStatus());\n                   found = true;\n               } \n         }\n if (! found)\n {\n  JOptionPane.showMessageDialog(null, \"Produto n\u00e3o encontrado\");\n}\n<\/code><\/pre>\n<\/p><\/div>\n
