Issue

I'm trying to use object Array in my project and i get an error :

incompatible types: Object cannot be converted to String

on this line :

ST1 = new String[]{emt1, emt2, emt3, emt4};

Now i don't figure out what is the cause of this error . please help me .

Object[] ST1;
Object emt1,emt2,emt3,emt4;


private void jButton3ActionPerformed(ActionEvent evt) {
    try {
        emt1 = null;
        emt2 = null;
        emt3 = null;
        emt4 = null;
        ST1 = new String[]{emt1, emt2, emt3, emt4};
    }
      ....

Solution

You have two way one is to cast every Object emt1, emt2, .. to String like this :

ST1 = new String[]{(String)emt1, (String)emt2, (String)emt3, (String)emt4};

Or you should to change the type of your attribute:

Object emt1, emt2, emt3, emt4;

To String

String emt1, emt2, emt3, emt4;
ST1 = new String[]{emt1, emt2, emt3, emt4};
