局部变量x重复

Question

我在for循环中遇到问题，说这是重复的局部变量？我仍在尝试了解这一点，并已尽我所能调查了答案，因此我现在向大家询问。如果您不介意，我想解释一下为什么它不起作用？int x = 3;String name = "Dirk";x = x * 17;System.out.print("x is " + x);double d = Math.random();while (x > 12) {    x = x - 1;}for (int x = 0; x < 10; x = x + 1) {    System.out.print("x is now " + x);}if (x == 10) {    System.out.print("x must be 10");} else {    System.out.print("x isn't 10");}if ((x < 3) & (name.equals("Dirk"))) {    System.out.println("Gently");}
