            System.out.println(f1.equals(f2));//line 1
            
            System.out.println(f2.equals(f3));
            
        }
    } 

does this f1 float value is promoted to double value for equlas() method evaluation

No, it doesn't convert the Floats to a double.

This is from the source code for Float.

    public boolean equals(Object obj) {
return (obj instanceof Float)
       && (floatToIntBits(((Float)obj).value) == floatToIntBits(value));
    }
