Integer.signum() Method in Java

This method returns the signum function of the specified int value. Now let's see the syntax.

int　signum(int　i)

This is the parameter.

• i-This is an int value

If the specified value is negative, it returns the value-1；If the specified value is zero, it returns 0; if the specified value is positive, it returns1.

Now let's look at an example.

Example

public　class　Demo　{
　　　public　static　void　main(String　[]args)　{
　　　　　　System.out.println("Returns　=　"+Integer.signum(0));
　　　　　　System.out.println("Returns　=　"+Integer.signum(-99));
　　　　　　System.out.println("Returns　=　"+Integer.signum(678));
　　　}
}

Output Result

Returns　=　0
Returns　=　-1
Returns　=　1
