Problem

Appending strings and ints

Select all lines that print 222.

System.out.println(1 + 1 + "2" + 2);
System.out.println(2 + 2 + "2");
System.out.println("2" + 2 + 2);
System.out.println("2" + 2 + 1 + 1);

Select one or more options from the list

[x] 1
[ ] 2
[x] 3
[ ] 4

Correct.

Hint & Explain

In this question,I learnt that integers act as integers,that is, they get added when they are in front of any character or string,but if they are present after any character,they act like strings and concatenate....😃
