Inside the two loops we make a new button, and for ease of reference the example puts text inside each button so we know which button in the two-dimensional array is where. The easiest way to do this is with two for loops, one for the x-axis, one for the y-axis. A Java DBGrid control - Open source Javabean grid to access database like sybase, oracle, db2, sql server using swing jtable. Now that it's been determined that there will be a certain number of buttons, each must be created.You need to add a line of code in the constructor that sets the amount: grid=new JButton Create a new row within the sheet and return the high level representation. The JButton's have been named, but we still have to say how many buttons there are. Java Programming Forums - The Java Community - The Friendly Java Community. Turns on or off the printing of gridlines.So basically each of your columns needs to have components with a total grid height of 3. The component will only go to grid 2 if the component above it has a grid height of 2. You cant just randomly assign a component to a grid. So right below the line where you create frame create the buttons: JButton grid The two sets of square brackets are there to say that the JButton's in the grid are kept in a two-dimensional format, if there were only one set of square brackets then it would simply be a line of JButton's, which still works, it's just easier to reference which button is being created or interacted with when it's two-dimensional. the text fields grid is binded to the list one, even tough the list is on y 1 and the text field on y 2. In the book Head First Java they use a 2d array. Boundary cases: In case in we reach out of the matrix, return from it. Base cases: Check If the bottom right cell, print the current path. Explore all the possible paths from a current cell using recursion and backtracking to reach bottom right cell. The buttons that the user interacts with need to be made, but since we don't know how many we need, they have to be named first. I'm trying to print a chess board grid but it's only printing the A file, then just prints out 7 more blank lines. Print all possible paths from top left to bottom right in matrix using Backtracking.
