其他方法中的eclipse自动getter和setter方法

Question

This is simple class implementation

class A{
private int a;
public void doSomething() {
    a = 5;
    int b = a;
    /*.
      .
      . */
}
/*
.
.
. */
}

now i'm using eclipse CTRL + 1 quick fix keybind and insert get and set mothod and codes will be this and this is option 1

class A{
private int a;
public void doSomething() {
    setA(5);
    int b = getA();
    /*.
      .
      . */
}
/*
.
.
. */
public int getA() {
    return a;
}
public void setA(int a) {
    this.a = a;
}
}

but if i want keep field codes will be this.(option 2)

class A{
private int a;
public void doSomething() {
    a = 5;
    int b = a;;
    /*.
      .
      . */
}
/*
.
.
. */
public int getA() {
    return a;
}
public void setA(int a) {
    this.a = a;
}
}

so which option is better for oop or code organization.

Answer 1

If you want to keep the normal assignment of a (ie a = 5; ) inside doSomething instead of using the setter ( setA(5) ), try creating the getters and setters using the refactoring key binding Alt + Shift + s and then select "Generate Getters and Setters".

If the only thing the setter does is assign the value to the field, there should be no difference between the two options.

Answer 2

If I understand you, then you could make int setA(int) also return a; , and then you can "chain" the method calls

public int setA(int a) {
  this.a = a;
  return a;
}

public void doSomething() {
  int b = setA(5);
}
