Use long instead of float in Capacity class to reflect proto buffer type

public class Capacity {

	// total capacity of hard disk

	private float total;

	private long total;

	// remaining capacity of hard disk

	private float remaining;

	private long remaining;

	public float getTotal() {

	public long getTotal() {

		return total;

	}

	public void setTotal(float total) {

	public void setTotal(long total) {

		this.total = total;

	}

	public float getRemaining() {

	public long getRemaining() {

		return remaining;

	}

	public void setRemaining(float remaining) {

	public void setRemaining(long remaining) {

		this.remaining = remaining;

	}

}
