Question

I have a Vector of Object[] type that stores my data. How to print all it’s objects ?

The code:

private static Vector<Object[]> vector = new Vector<Object[]>();


int event=0;
for(int i=0; i<10; i++){
    vector.add( this.addToObject(System.currentTimeMillis(), event , "String") );
    event++;    
}

private Object[] addToObject(long t, int i,String s ){
    Object[] o = new Object[4];
    o[3] = s;
    o[2] = i;
    o[1] = "00000";
    o[0] = t;
    return o;
}

printing

public static void main(String[]args){
    main m = new Main();

    for(int i=0; i< m.vector.size(); i++){

    }

}

And I’d like to get sth like this :

1202393057117 1 OOOOO String
1202393057117 2 OOOOO String
1202393057118 3 OOOOO String
1202393057118 4 OOOOO String
1202393057118 5 OOOOO String

Inside your printing for loop:

Object[] objs = vector.get(i);
for (Object o : objs) {
    System.out.print(o + " ");
}
System.out.println();
