Java Float hashCode() method

The hashCode() method of Java Float class returns the hash code for this Float. The result is represented as integer bit representation whose value is same as produced by the floatToIntBits(float) method. The hashCode() method of Float class overrides the hashCode() method of class Object.

Syntax:

Parameters:

• NA
• The value provided to hash.

Return Value:

This method returns a hash code value for this float object.

Example 1

Output:

1. Hash Value = 0

2. Hash Value = 1143586816

3. Hash Value = 1143586818

4. Hash Value = -1003896832

Example 2

Output:

Enter your admission No
1197
Your id is : 1150656512

Enter your admission No
1198
Your id is : 1150664704

Example 3

Output:

HAsh code value = 1119617024
Float value  = 1119617024

Example 4

Output:

Error:(11, 30) java: incompatible types: int cannot be converted to java.lang.Float

Note: Here with hashCode() method, we are converting the object into int bits and without any explicit cast, we are putting it into Float, so it is giving us an error. Either we should typecast it or should directly call this method in println function.
