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;
//  }
}
