“java variable might not have been initialized”错误表明在Java程序中,某个变量在使用前可能没有被正确初始化。在Java中,局部变量(即定义在方法、代码块或构造函数内部的变量)必须在使用之前进行初始化,否则编译器会抛出此错误。 导致此错误的常见情况 忘记初始化变量:程序员在声明变量后,忘记了在使用之前为其赋...
int position_before = 0, position_after = 0, smallVowel = 0, largeVowel = 0;建议你用eclipse来写java代码，这样出错的时候IDE会自动提示，一目了然

The local variable...been initialized 局部变量如果不初始化,里面的就是一些垃圾值。如果你再方法里用到了,有可能造成运行错误,这种错误很难找到。 所以Java要求变量必须初始化,其中实例变量和类变量有默认的初始值。 给变量一个初始化,是一个良好的编程习惯,而Java的编译器只不过做的极端一些,强制你养成良好的...
