Operator overloading in Java
...an example is worth a thousand arguments. Given m0 as a Matrix and v0, v1, v2, v3, and v4 as Vectors, simply compare how long it takes you to correctly interpret the following mathematical expression m0.transpose().mult(v0.add(v1.mult(v2)).cross(v3)).sub(v4);. Had support for operator overloading be...
