# Running Java code

## Calling methods

{% tabs %}
{% tab title="Syntax" %}

```
%object%.<method name>(%objects%)
```

{% endtab %}

{% tab title="example.sk" %}

```
event-block.breakNaturally()
(last spawned creeper).setPowered(true)
player.giveExpLevels({_levels})
```

{% endtab %}
{% endtabs %}

Methods may be used as effects, expressions, and conditions. If used as a condition, the condition will pass as long as the return value of the method is not `false`, `null`, or `0`.

### Calling non-public methods

If the method you're trying to invoke is not public, you must prefix the method name with the declaring class in brackets. Since an object may have a non-public method with the same name in multiple superclasses, you must explicitly specify where to find the method.

{% code title="example.sk" %}

```
{_arraylist}.[java.util.ArrayList]fastRemove(1)
# or, if you have the declaring class imported:
{_arraylist}.[ArrayList]fastRemove(1)
```

{% endcode %}

### Calling overloaded methods

Generally, skript-mirror can infer the correct overloaded method to call from the arguments passed at runtime. If you need to use a certain implementation of a method, you may append a comma separated list to the end of the method name surrounded in brackets.

{% code title="example.sk" %}

```
System.out!.println[java.lang.Object]({_something})
# or, if you have the parameter classes imported:
System.out!.println[Object]({_something})

Math.max[int, int](0, {_value})
```

{% endcode %}

## Calling fields

{% code title="Syntax" %}

```
%object%.<descriptor>!
```

{% endcode %}

{% hint style="info" %}
References to fields must end in `!` due to limitations in Skript's parser.
{% endhint %}

### Calling non-public fields

If the field you're trying to use is not public, you must prefix the field name with the declaring class in brackets. Since an object may have a non-public field with the same name in multiple superclasses, you must explicitly specify where to find the field.

{% code title="example.sk" %}

```
{_hashmap}.[java.util.HashMap]modCount!
# or, if you have the declaring class imported:
{_hashmap}.[HashMap]modCount!
```

{% endcode %}

## Calling constructors

{% tabs %}
{% tab title="Syntax" %}

```
[a] new %javatype%(%objects%)
```

{% endtab %}

{% tab title="example.sk" %}

```
new Location(player's world, 0, 0, 0)
```

{% endtab %}
{% endtabs %}
