How To Find A Path Through Array Maze

So what I'm trying to do is write a code in java which finds a path through a maze. I want it to go through the maze and determine if there's a * symbol at that location or not. If there is a * symbol at the specified location then the program would search for another position until it finds one without the * symbol and if it can't then I'll have the program return null. I also want it to implement backtracking which I'm not sure how to do. Here's my code so far

private boolean findPath(int fromRow, int fromCol, int toRow, int toCol){
boolean solved = true;
for(int i=fromRow; i<toRow; i++){
for(int j=fromCol; j<toCol; j++){
if (x[i][j] == ('*')){
//do something
}
}
}
return false;
}

the code isn't finished yet however what I'm not sure is what do I do with the if statement and how do I implement backtracking?
