Question

// package ClassObjectsandMethod;
class Methodoperator
{
static float mul(float x,float y)
{
return x*y;
}
static float div(float x,float y)
{
return x/y;
}
}
public class StaticMember {
public static void main(String[] args) {
float a = Methodoperator.mul(4.0,5.0); //Why an error here
float b = Methodoperator.div(a,5.0); //& here
}
}
Why this error show ....
StaticMember.java:15: error: incompatible types: possible lossy conversion from double to float
float a = Methodoperator.mul(4.0,5.0);
^
StaticMember.java:16: error: incompatible types: double cannot be converted to Float
float b = Methodoperator.div(4.0,5.0);
^

Answer 1

Hello Kriti_shrivastava

4.0 and 5.0 are doubles. You have to add F to each number to treat them as float:

float a = Methodoperator.mul(4.0F, 5.0F);
float b = Methodoperator.div(4.0F, 5.0F);
