You may see this error for writing wrong expression to initialize an array. See the code below:

int data={42,15,27,20,19};

If you compile this, you will see the following error message:

illegal initializer for int
int data={42,15,27,20,19};
^

Here the array is not declared properly as we have not put [ ] for declaring the array. The correct code is:

int data[ ]={42,15,27,20,19};

or

int[ ] data={42,15,27,20,19};


If the above solutions do not work for you. Please comment below giving your code. I'll try to respond.

  1. What about String[] x = {{"NewDelhi","Rs"},
    {"Islamabad","Rs"},
    {"London","Euro"},
    {"Washington","Dollar"}};

    It is also producing same error. . .
    Reason. . . ????

  2. Here two dimensional String values are assigned to one dimensional array.

    Correct code will be:

    String[][] x = {{"NewDelhi","Rs"},
    {"Islamabad","Rs"},
    {"London","Euro"},
    {"Washington","Dollar"}};

    1. Correct code would be:
      for(int i = 0; i<myList.length; i++)
