{ "Tweaks" : 99999999999, "X" : 77.58, "Y" : 46.14, "Count" : 99999999999, "Key" : "OemComma", }

Here's how you can represent the given JSON object in Java:

```java
import com.google.gson.annotations.SerializedName;

public class Tweaks {
    @SerializedName("Tweaks")
    private long tweaks;

    @SerializedName("X")
    private double x;

    @SerializedName("Y")
    private double y;

    @SerializedName("Count")
    private long count;

    @SerializedName("Key")
    private String key;

    public Tweaks() {}

    public Tweaks(long tweaks, double x, double y, long count, String key) {
        this.tweaks = tweaks;
        this.x = x;
        this.y = y;
        this.count = count;
        this.key = key;
    }

    public long getTweaks() {
        return tweaks;
    }

    public void setTweaks(long tweaks) {
        this.tweaks = tweaks;
    }

    public double getX() {
        return x;
    }

    public void setX(double x) {
        this.x = x;
    }

    public double getY() {
        return y;
    }

    public void setY(double y) {
        this.y = y;
    }

    public long getCount() {
        return count;
    }

    public void setCount(long count) {
        this.count = count;
    }

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }

    @Override
    public String toString() {
        return "Tweaks{" +
                "tweaks=" + tweaks +
                ", x=" + x +
                ", y=" + y +
                ", count=" + count +
                ", key='" + key + '\'' +
                '}';
    }
}
```

You can use the `com.google.gson` library to parse the JSON string into a `Tweaks` object:

```java
import com.google.gson.Gson;

public class Main {
    public static void main(String[] args) {
        String jsonString = "{\"Tweaks\":99999999999,\"X\":77.58,\"Y\":46.14,\"Count\":99999999999,\"Key\":\"OemComma\"}";
        Gson gson = new Gson();
        Tweaks tweaks = gson.fromJson(jsonString, Tweaks.class);
        System.out.println(tweaks);
    }
}
```

Alternatively, you can use the `com.fasterxml.jackson.databind` library to achieve the same result:

```java
import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        String jsonString = "{\"Tweaks\":99999999999,\"X\":77.58,\"Y\":46.14,\"Count\":99999999999,\"Key\":\"OemComma\"}";
        ObjectMapper mapper = new ObjectMapper();
        Tweaks tweaks = mapper.readValue(jsonString, Tweaks.class);
        System.out.println(tweaks);
    }
}
```
