java - javaFx radio button and textfield user selection and user input -
so question trying implement gui has 4 radio buttons let user choose type of sorting want do(quick,insertion,bubble,selection) , can pick 3 more radio buttons , choose either sorted, random, reverse sorted. has textfield allows them chose input size of array , block size. after user has chosen radio buttons , put in information input size text field , block size text field, hit go , program sort array , output sorted array console.
so need implementing action event or listener go button information radio buttons , text fields. understand logic behind wasn't sure how link event handler/action event. code far compiles , when hit 'go' button prints array of 100 numbers sorted in order 1-100. doesn't take account user selects on radio buttons or text field's block size , input size , need that. here code:

your potential radio options are:
"selection, sorted":"selection,reverse":...:"quick, random"
you need handle of different cases have have between 2 togglegroups.
if(selection.isselected() && sorted.isselected()){ int arraysize = integer.parseint(inputtext.gettext()); int[] array = getsorted(arraysize,true); print(array); int loopcount = selectionsort(array); } else if(selection.isselected() && reverse.isselected() { //do } else if(...) { } . . . else if(quick.isselected() && random.isselected()) { //do } added due updated comment
now print method should like:
public static void print(int[] array, int blocksize) { (int = 0; < array.length; i++) { system.out.print(" " + array[i]); if((i + 1) % blocksize == 0) { system.out.println(); } } system.out.println(); } and old call print methods change from:
print(array); to:
print(array, integer.parseint(block.gettext()));
