java - Java 中的设置方法

Question

有人可以解释一下如何使用 set 方法吗？问题:

class Sonum {
   private int prior;
   public Sonum(int prior) {
      this.prior = prior;
   }
   public int getPrior() {
      return prior;
   }
   public void setPrior(int prior) {
      this.prior = prior;
   }

class Tel {
   // Please explain how can I set the value for prior? (for example 2)
}

Answer 1

首先，您需要一个要在其上设置prior 值的Sonum 实例。例如:

class Test {
  public void foo() {
    Sonum sonum = new Sonum(5);
    // Use it with a prior of 5
    // ...
    sonum.setPrior(10);
    // Now use it with a prior of 10
  }
}
