If a class defines one or more constructor methods, Java does not provide the default constructor.

Class Trapezoid
{
Float upper bottom, lower bottom, high;
 
Trapezoid (float X, float y, float H)
{
Bottom = X;
Bottom = y;
Height = h;
}
Float calculation area ()
{
Float area;
Area = (upper bottom + lower bottom) * High/2.0f;
Return area;
}
Void height (float height)
{
Height = height;
}
Float get high ()
{
High return;
}
}
Class Area
{
Public static void main (string ARGs [])
{
Trapezoid ladertwo = new trapezoid (2.0f, 3.0f, 10.0f );
// Lader = new trapezoid ();
// Ladertwo = new trapezoid (2.0f, 3.0f, 10.0f );
// System. Out. println ("lader" + lader. Get high ());
System. Out. println ("ladettwo" + ladertwo. Get high ());
// System. Out. println ("lader" + lader. Calculated area ());
System. Out. println ("ladertwo" + ladertwo. Calculated area ());
// Lader. Modify height (10 );
Float H = 2.0f;
Ladertwo. Modify height (H * 2 );
// System. Out. println ("lader's current height" + lader + "ladertwo's current height" + ladertwo );
// System. Out. println ("Current lader area" + lader. Calculated area () + "Current lader. Two area" + ladertwo. Calculated area ());
}
