形参和实参

package lianxii;

class OneT {

    private final int a = 1;

    public int geta(int b) {//int b为形参

        return a * b;//跟返回也有关
    }

    public static void main(String[] args) {

        int ii = 2;
        OneT p = new OneT();
        int pp = p.geta(ii);//ii为实参
        System.out.println(pp);

    }
}
