required variable, found String java

I am trying to read in a user input as a string. Parse it into an int, then whatever number (0-3) that the user input, I want to replace that index of the array with a card. Here is the code

    public void discard(String text) {

    int i = Integer.parseInt(text);

    for(int p = 0; p < 4; p++){
        if(i == p){
            hand[p].getCard() = card; // This is where I recieve the Error.
        }
    }
}

Anything that will help me correct and understand my mistake will be helpful, Thanks!

Without seeing your code, you're probably going to to need to change:

hand[p].getCard() = card;

to

hand[p].setCard(card);

You can't assign to a getter.

Also, this code:

for (int p = 0; p < 4; p++) {
    if (i == p){
        // do something with p
    }
}

Can be replaced with

// do something with i

I think you meant to do this

hand[p].setCard(card);

because the below piece of code doesn't really make sense. You can't possibly assign a value to a value(retrieved by getCard()) method. That is why you got the error that it expected a variable on the left hand side of the assignment operator, but instead found a String there.

hand[p].getCard() = card;
