Two polygons are said to be similar if their corresponding angles are the same or if each pair of corresponding sides has the same ratio. Write the code to test if two right triangles are similar when the measurement of each side is provided as an integer value. If one set of corresponding sides of the triangles have lengths of 18 and 12, the ratio would be 1.5. The output needs to display the ratio for each set of sides and a message stating if the triangles are similar or not.

*Note: This needs to be coded in Java and I'm currently using BlueJ terminal
