This program is suppose to calculate area and perimeter of a rectangle and an applet to test it.
When I run the program I can input the length and width, but the computer does not do any calculations
I can not figure it out
Thank you for your help and time

Here the x and y are local to the methods,setting those values will not have any effect in mainx and mainy.try setting the mainx and mainy values instead of x and y in the setter methods....

you have done a small mistake.
in your setLength you are assigning value to x and y
change that to mainX and mainY. Then your program will display wt u want.
public void setLength(float x) // set length
{
mainX = ((x >= 1 & x < 20) ? x : 1); // range validation
}
public void setWidth(float y) // set width
{
mainY = ((y >= 1 & y < 20) ? y : 1); // range validation
}
