public class Chapter8 { public static void main(String args[]) { Float f1 = new Float(1.0f); //1 Float f2 = new Float(1.0); //2 Float f3 = new Float("1.0"); //3 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)); }
