Answer / hasini

simple steps:


String s1 = "Hello, ";
String s2 = "world!";
String s3 = s1 + s2;
System.out.println(s3);
// prints out: Hello, world!

1) int i=5; j=i++ + i++ + i++; printf("%d",j);This code gives the answer 15.But if we replace the value of the j then anser is different?why? 2)int i=5; printf("%d",i++ + i++ + i++); this givs 18.
