Java 如何在我的代码中添加一个名为categories的新数组，并将其与保存到数组中的文本文件中的代码一起打印出来
现在我想在代码中添加一个名为“category”的新数组。我应该添加一个数组，并可以让它与我的其他代码一起打印出来。我已经尝试过2014年类别的if声明。它告诉我没有语法错误，但是没有任何内容正在打印。我还想格式化我的代码，使它们都列在列中，看起来井然有序。我尝试了一些方法，但没有任何改变。我现在所说的没有格式，没有那么重要，但如果有人能帮忙，我将非常感激Java 如何在我的代码中添加一个名为categories的新数组，并将其与保存到数组中的文本文件中的代码一起打印出来,java,arrays,if-statement,Java,Arrays,If Statement,现在我想在代码中添加一个名为“category”的新数组。我应该添加一个数组，并可以让它与我的其他代码一起打印出来。我已经尝试过2014年类别的if声明。它告诉我没有语法错误，但是没有任何内容正在打印。我还想格式化我的代码，使它们都列在列中，看起来井然有序。我尝试了一些方法，但没有任何改变。我现在所说的没有格式，没有那么重要，但如果有人能帮忙，我将非常感激 enter code here /** * Write a program to calculate the average catego

您应该将if-else嵌套语句改为循环Ok，这对我也有帮助。让我编写代码更简单，非常感谢。
