java - 如何通过 OOP 打印多个值而不用在 Java 中添加它们

Question

我想要的是打印出这些方法中的每一个，而不是将它们的值加在一起。我认为这就是为什么我在尝试将 boolean 值放入第一个 System.out 语句中时出错的原因。我是否必须为每个人提供自己的 System.out.println 语句？

public class Main {
public static void main(String[] args)
{
    Block dirt = new Block(1, 100, 1, false, false, 0, 1, 100, 1)
    {

    };
    System.out.println(dirt.getSpawnLevel() + dirt.getSize() + dirt.getHardness() + dirt.getOpacity() + dirt.getRarity() + dirt.getBounceHeight() + dirt.getStackSize());

    System.out.println(dirt.getFlammable());
    System.out.println(dirt.getBlockBounce());

}

}

Answer 1

Block dirt = new Block(1, 100, 1, false, false, 0, 1, 100, 1)
    {

    };

将之前的代码更改为:

Block dirt = new Block(1, 100, 1, false, false, 0, 1, 100, 1);

还可以像这样打印输出:

System.out.println(dirt.getSpawnLevel()+"," + dirt.getSize()+"," + dirt.getHardness()+"," + dirt.getOpacity()+"," + dirt.getRarity()+"," + dirt.getBounceHeight()+"," + dirt.getStackSize());
