Answer 1

The numbers written after string literal are regarded as string. So here Strings are concatenated

Answer 2

Sharan⚜️

After String if you add any number then it will just concat with string.

So if you want 4=4 then just add brackets ( ) before and after the number like

1 + 3 + "=" + (1 + 3)

Answer 3

To get 4=4
System.out.println((1+3)+"="+(1+3));

Answer 4

Oh ok got it buddy thnks👍🏻

Answer 5

From my analysis,
System.out.println(1+3+"="+1+3);
First it starts from beginning, here it found 1+3 and both are integer so it adds them and 1+3=4.Then the next value is a string.So it adds 4+"=" which is "4="
The next number is 1 which is an integer and it adds with the string "4=" and becomes "4=1" .Now "4=1" is a string and the next value 3 is an integer.So it adds with "4=1" to int 3 and becomes "4=13".
This is just my prediction .I am not sure with my theory.
