To assign a value to a variable in Java you write:
<variable name> = <expression>;
Remember that = means assignment action, whereas == means equality relation.
distance = sqrt( dx*dx dy*dy ); //calculate distance based on dx and dy k = uniform_discr( 0, 10 ); //set k to a random integer between 0 and 10 inclusive customer = null; //"forget" customer: reset customer variable to null ("nothing")
The shortcuts for frequently used assignments can be executed as statements as well (see Arithmetic expressions), for example:
k ; //increment k by 1 b *= 2; //b = b*2
