java - How to find a certain criteria from various text fields and display a match off from a text file? -
i supposed make inventory program gui. code can far open file. however, need make displays files match criteria. main problem text file sorted in weird way necessary decode.
so if put: bmw in make field, 21123 serial number, muffler name, 119.99 price, , 0 stock. should first 5 lines in text area.
how find criteria various text fields , display match off text file?
bmw muffler 21123 119.99 0 chevy muffler 20911 52.99 2 ford muffler 26854 129.59 2 honda muffler 23319 159.99 2 toyota muffler 27813 199.29 1 bmw catalytic converter 900122 132.33 2 chevy catalytic converter 902391 69.59 1 ford catalytic converter 905778 61.23 4 code

jtable , rowsorter should solution.
perhaps code useful too.
public void search() { string s = tf.gettext(); string content = textarea.gettext(); // instead file int index = content.indexof(s, 0); if (index >= 0) { try { int end = index + s.length(); // } }
