In Java, the expression "number" +6+4*5 produces which of the following string literals?

Question

a."number645"
b."number105"
c."number50"
d.number620"
e."number26"

Answer 1

c. "number" is a String, + is a string concatenation and * is a integer only operation. So you have two string concatenations putting together "number" "6" and "20". You can test it with this programm call the file Main.java and put following code into it:

public class Main(){
public static void main(String[] args){
System.out.println("number"+6+4*5);
}
}

Compile and run and you will see the result in the console. Hope this helps

Answer 2

The answer is d.

But you know that now because you have run the test.
