Für

import java.util.Vector;
import java.lang.Integer;

public class mathStruc {
model;

innerOp = (o) -> (ms) -> new mathStruc<>(o.apply(model,ms.model));

public mathStruc(m) {
	model =m;
}

}

und

//package de.test;

import java.util.Vector;
import java.lang.Integer;
import java.lang.Boolean;

import mathStruc;
import vectorAdd;

public class mathStrucVector {

public main() {
Vector v1 = new Vector();
v1.addElement(2);
v1.addElement(2);
Vector v2 = new Vector();
v2.addElement(3);
v2.addElement(3);

	vectorAdd va = new vectorAdd();

	var ms;
	ms = new mathStruc<>(v1);
	var ms2;
	ms2 = new mathStruc<>(v2);
	var ms3;
	
	//ms3 = ms.innerOp.apply(va.add).apply(ms2);
	//return ms3;

}
}

wird folgneder Bytecode erzeugt
