如何避免出现“本地变量可能尚未初始化”的Java编译错误？（是的，很认真！）

通过向编译器提供一些额外的信息来欺骗一些用户：

final int x;try {    x = blah();} catch (MyPanicException e) {    abandonEverythingAndDie();    throw new AssertionError("impossible to reach this place"); // or return;}System.out.println("x is " + x);

您还可以使

abandonEverythingAndDie()

returnabandonEverythingAndDie()

final int x;try {    x = blah();} catch (MyPanicException e) {    return abandonEverythingAndDie();}System.out.println("x is " + x);

和方法：

private static <T> T abandonEverythingAndDie() {    System.exit(1);    throw new AssertionError("impossible to reach this place");}

甚至

throw abandonEverythingAndDie();

与

private static AssertionError abandonEverythingAndDie() {    System.exit(1);    throw new AssertionError("impossible to reach this place");}
