final的初始化

public class FinalTest {//在定义变量的时候直接初始化private final int a = 1;//在构造方法内进行初始化private final int b;public FinalTest() {    b = 1;}//在构造代码块中初始化private final int c;{    c = 1;}//在静态代码块中初始化private static final int d;static{    d = 1;}//不能在构造方法中进行初始化//  private static final int e;//  public FinalTest() {//      e = 1;//  }}
