Field Summary

Fields
Modifier and Type	Field and Description
`static boolean`	`JAVA_11_REFLECTION_SUPPORTED` True if `JAVA_11_SERIALIZATION_SUPPORTED` is true and the call `Class.forName("java.lang.reflect.Method")` works without exception.
`static boolean`	`JAVA_11_SERIALIZATION_SUPPORTED` True if Integer class implements an interface named "java.io.Serializable".
`static boolean`	`JAVA_12_COLLECTIONS_SUPPORTED` True if all `JAVA_11_SERIALIZATION_SUPPORTED`, `JAVA_11_REFLECTION_SUPPORTED` and `JAVA_12_COMPARABLE_SUPPORTED` constants are true and if Java 2 collections (`java.util.Map`, `java.util.HashMap`, etc.) are found.
`static boolean`	`JAVA_12_COMPARABLE_SUPPORTED` True if both `JAVA_11_SERIALIZATION_SUPPORTED` and `JAVA_11_REFLECTION_SUPPORTED` constants are true and if Integer class implements an interface named "java.lang.Comparable".

- Field Detail
  - JAVA_11_SERIALIZATION_SUPPORTED
```
public static final boolean JAVA_11_SERIALIZATION_SUPPORTED
```
    True if Integer class implements an interface named "java.io.Serializable".
    Can be used to detect Java 1.1 compatibility.
  - JAVA_11_REFLECTION_SUPPORTED
```
public static final boolean JAVA_11_REFLECTION_SUPPORTED
```
    True if JAVA_11_SERIALIZATION_SUPPORTED is true and the call Class.forName("java.lang.reflect.Method") works without exception.
    Can be used to detect Java 1.1 compatibility with more assurance than JAVA_11_SERIALIZATION_SUPPORTED.
  - JAVA_12_COMPARABLE_SUPPORTED
```
public static final boolean JAVA_12_COMPARABLE_SUPPORTED
```
    True if both JAVA_11_SERIALIZATION_SUPPORTED and JAVA_11_REFLECTION_SUPPORTED constants are true and if Integer class implements an interface named "java.lang.Comparable".
    Can be used to detect Java 1.2 compatibility.
  - JAVA_12_COLLECTIONS_SUPPORTED
```
public static final boolean JAVA_12_COLLECTIONS_SUPPORTED
```
    True if all JAVA_11_SERIALIZATION_SUPPORTED, JAVA_11_REFLECTION_SUPPORTED and JAVA_12_COMPARABLE_SUPPORTED constants are true and if Java 2 collections (java.util.Map, java.util.HashMap, etc.) are found.
    Can be used to detect Java 1.2 compatibility with more assurance than JAVA_12_COMPARABLE_SUPPORTED.
