Examples


package com.logicbig.example.clazz;

public class GetTypeNameExample {

    public static void main(String... args) {
        Class<GetTypeNameExample> c = GetTypeNameExample.class;
        System.out.println("TypeName: " + c.getTypeName());
        System.out.println("Name: " + c.getName());
        System.out.println("SimpleName: " + c.getSimpleName());
        System.out.println("CanonicalName: " + c.getCanonicalName());
    }
}

Output

TypeName: com.logicbig.example.clazz.GetTypeNameExample
Name: com.logicbig.example.clazz.GetTypeNameExample
SimpleName: GetTypeNameExample
CanonicalName: com.logicbig.example.clazz.GetTypeNameExample




package com.logicbig.example.clazz;

public class GetTypeNameExample2 {

    public static void main(String... args) {
        System.out.println("-- int[] --");
        Class<int[]> c = int[].class;
        System.out.println("TypeName: " + c.getTypeName());
        System.out.println("Name: " + c.getName());
        System.out.println("SimpleName: " + c.getSimpleName());
        System.out.println("CanonicalName: " + c.getCanonicalName());

        System.out.println("-- Integer[] --");
        Class<Integer[]> c2 = Integer[].class;
        System.out.println("TypeName: " + c2.getTypeName());
        System.out.println("Name: " + c2.getName());
        System.out.println("SimpleName: " + c2.getSimpleName());
        System.out.println("CanonicalName: " + c2.getCanonicalName());

    }
}

Output

-- int[] --
TypeName: int[]
Name: [I
SimpleName: int[]
CanonicalName: int[]
-- Integer[] --
TypeName: java.lang.Integer[]
Name: [Ljava.lang.Integer;
SimpleName: Integer[]
CanonicalName: java.lang.Integer[]
