I have the following txt fil, I'm wondering how can I pars it and search for Cell And Engin words, what I want is to print out the method name that contains Cell, Engine words. the following is the txt file don't look at it as java code since I already moved it to txt file for parsing purposes.

@Test
public void testGetMonsters() {
Cell cell11 = aBoard.getCell(1, 1);
theEngine = new Engine(theGame);
}

@Test
public void testDxDyPossibleMove() {
Cell cell11 = aBoard.getCell(1, 1);
}
the output of parsing looks like: testGetMonsters method contains Cell and Engine words
testDxDyPossibleMove method contains Cell word
