float variables initialization java

Question

The following code snippet gave me compiler error at Line 1.

public abstract class xyz
{

    float Gamma = 20.0; //Line 1
    public class Alpha
    {
        v         


        

Answer 1

In Java by default decimal values are stored as double. But for storing it as a floating point number we explicitly need to declare, like

float varName = 10.0f; or float varName = (float)10.0;
