So I wrote the program below, but

Answer 1

Here is my solution please try and let me know

package thread;

class SyncPrinter {
    public static void main(String[] args) {
        SyncPrinterAction printAction1 = new SyncPrinterAction(new int[]{1,5,9,13}, true);
        SyncPrinterAction printAction2 = new SyncPrinterAction(new int[]{2,6,10,14}, true);
        SyncPrinterAction printAction3 = new SyncPrinterAction(new int[]{3,7,11,15}, true);
        SyncPrinterAction printAction4 = new SyncPrinterAction(new int[]{4,8,12,16}, false);

        printAction1.setDependentAction(printAction4);
        printAction2.setDependentAction(printAction1);
        printAction3.setDependentAction(printAction2);
        printAction4.setDependentAction(printAction3);

        new Thread(printAction1, "T1").start();;        
        new Thread(printAction2, "T2").start();
        new Thread(printAction3, "T3").start();     
        new Thread(printAction4, "T4").start();



    }
}

class SyncPrinterAction implements Runnable {

    private volatile boolean dependent;
    private SyncPrinterAction dependentAction;
    int[] data;

    public void setDependentAction(SyncPrinterAction dependentAction){
        this.dependentAction = dependentAction;

    }

    public SyncPrinterAction( int[] data, boolean dependent) {
        this.data = data;
        this.dependent = dependent;
    }

    public SyncPrinterAction( int[] data, SyncPrinterAction dependentAction, boolean dependent) {
        this.dependentAction = dependentAction;
        this.data = data;
        this.dependent = dependent;
    }

    @Override
    public void run() {
        synchronized (this) {

            for (int value : data) {

                try {
                    while(dependentAction.isDependent())
                        //System.out.println("\t\t"+Thread.currentThread().getName() + " :: Waithing for dependent action to complete");
                    wait(100);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

                dependentAction.setDependent(true);

                System.out.println(Thread.currentThread().getName() + " :: " +value);
                dependent = false;
            }

        }

    }

    private void setDependent(boolean dependent) {
        this.dependent = dependent;

    }

    private boolean isDependent() {
        return dependent;
    }

}
