Generics, Consuming - in COBOL and Java

Consuming Generics in Managed COBOL

*> Consuming a generic method via type inference

01 result as type Tuple[binary-long binary-long].
*> Parameters are used to infer type
set result to type Tuple::Create(1 2)

*> Consuming a generic collection
01 x type List[string] value new List[string].
01 i binary-long.
01 val string.
procedure division.
    perform varying i from 0 by 1 until i greater than 100
       invoke x::Add(i::ToString)
    end-perform
    perform varying val through x
       display val
    end-perform

Consuming Generics in Java

// Consuming a generic method 
HashMap<Integer, Integer> result; 

result = new HashMap<Integer, Integer>(1, 2);

//Consuming a generic collection
List<String> x = new ArrayList<String>();
	
for(Integer i = 0; i < 101; ++i)
{
    x.add(i.toString());
}
for(String val : x)
{
    System.out.println(val);
}
