Java - If 语句问题 - 更改条件会删除下面的其他语句

Question

IT 世界的新手，有一些初学者的问题。因此，我正在学习一些教程，并遇到了一个我自己无法解决的问题。代码如下:

    boolean gameOver = true;
    int score = 5000;
    int levelCompleted = 5;
    int bonus = 100;

        if(score == 5000)
            System.out.println("Your score is 5000");

    if(score > levelCompleted){
        System.out.println("Score is greater that levelCompleted");
        System.out.println("5000 is greater that 5");
        System.out.println("Some new text on true condition");
        }

    if(score<5000){ 
        System.out.println("Score is equal to 5000");
        }
        else
        { 
        System.out.println("Condition is false");
        }

    if((score < 5000) &&  (score > 1000)){ 
        System.out.println("Both conditions are true"); 
        }
        else if(score<1000)
        { 
        System.out.println("Else if condition is true"); 
        }
        else
        { 
        System.out.println("None of the condtitions are true!");


    if(gameOver == true){ 
        int finalScore = score + (levelCompleted * bonus);  
        System.out.println("Your final score was " + finalScore);
        }


    if(gameOver == true){
        score = 10000; 
        levelCompleted = 8;
        bonus = 200;
        int finalScore= score + (levelCompleted * bonus);
        System.out.println("Your final score was " + finalScore);
        }


    System.out.println(score);
    }

    System.out.println(levelCompleted);

    }

}

上面代码的输出显示了预期的结果，它们是:

Your score is 5000
Score is greater that levelCompleted
5000 is greater that 5
Some new text on true condition
Condition is false
None of the condtitions are true!
Your final score was 5500
Your final score was 11600
10000
8

但是，当我更改 if/else if/else 语句的 if 条件时

 if ( (score < 5000) &&  (score > 1000) )

至

if( (score == 5000) &&  (score > 1000) )

如您所见，我仅从 < 更改为 == ，并且得到以下输出。

Your score is 5000
Score is greater that levelCompleted
5000 is greater that 5
Some new text on true condition
Condition is false
Both conditions are true
5

那么，下面的另外两个 if-s 发生了什么？

最后两个“独立”system.out.println-s 在哪里？

另外，5现在从哪里来？我想来自 levelCompleted 变量，但是如何呢？

预先感谢您的帮助和解释!

缺少}。请参阅贾斯珀的评论。如果使用 Eclipse，请使用 Ctrl + Shift + F 自动设置代码格式。
