how can I print from the java class one bye one-CodePudding

in the main

else if(user ==3) {
            
            
            todolists.Displayitem();
            duedatelists.Displayitem();
            prilists.Displayitem();
            System.out.println("");
            
            
            
        }

in the class Todo

public void Displayitem() {
        if(todolist.size()==0) {
            System.out.println("All Done !!!");
        }else {
        System.out.println("To Do List");
        int index =1;
        for(String item: todolist) {
            System.out.print("("  index    ")" item  " ");
        }
        
        }
    }

I think it would print something like (1) test 1 DATE mmddyy LEVEL (2) test 2 DATE mmddyy LEVEL

but it prints (1) test1 (2) test2 DATE DATE LEVEL LEVEL

CodePudding user response：

You need to remove the following lines from main and put them in DisplayItem

        duedatelists.Displayitem();
        prilists.Displayitem();
        System.out.println("");

CodePudding user response：

It seems you have three lists to print:

todolists.Displayitem();
duedatelists.Displayitem();
prilists.Displayitem();

However you want information from all three lists printed together. So how about assuming that you have an equal number of entries in all three lists, then you can do

for (int i=0;i<todolists.size()) {
   System.out.print(i);
   System.out.print(todolists.get[i]);
   System.out.print(duedatelists.get[i]);
   System.out.print(prilists.get[i]);
}

You will have to add whitespace/formatting to your taste to make it readable though.
