1.

class ***{
System,out.println(" " + 2 +3 );
System,out.println(2 +3);
System,out.println(2 +3 + " ");
System,out.println(2 + " " +3 );
}

Gives error has : Type Expected.

2.class Test{
System.out.println( -1 * Double.NEGATIVE_INFINITY);

}

Does nor compile.

It would be helpful if I get an explanation.
