Shouldn't the 4th example be correct?

Syntax error on tokens, Expression expected instead for
public static void main(String[] args) {

cab ola =() ->System.out.println("Hello"); //Multiple markers at this line
- Syntax error on tokens, Expression expected instead
- Syntax error, insert ")" to complete Expression
}

[@kishorep5572]

Did you defined Cab as functional interface with zero argument method

[@Sigma-Coding-dm3it]

plz sir: you declare m1 void so it should not return a value:..........public int m1(int a){ return a*a;}
the return type should be int and not void.
