Exercise 7 – Addition expression

The program statements needed to carry out a simple addition are surprisingly complicated. Suggest why the Java programming language does not allow a pair of additions to be written simply:

2+2 3+3

rather than

System.out.println( "2+2 is" );
System.out.println( 2+2 );
System.out.println( "3+3 is" );
System.out.println( 3+3);
