How to check size of arrayin java

if ( playerCt == playerList.length ) {
        // The number of players is already equal to the size of the array.
        // The array is full.  Make a new array that has more space.
    Player[] temp;   // A variable to point to the new array.
    temp = new Player[ 2*playerList.length ];  // Twice as big as the old array.
    for ( int i = 0; i < playerList.length; i++ ) {
        temp[i] = playerList[i];  // Copy item from old array into new array.
    }
    playerList = temp;  // playerList now points to the new, bigger array.    
}
