Java mixed numeric + String concatenation: evaluate left-to-right and determine the printed result.\n\nclass Q207 {\n public static void main(String[] args) {\n int i1 = 5;\n int i2 = 6;\n String s1 = "7";\n System.out.println(i1 + i2 + s1); // Line 8\n }\n}

Introduction / Context:
This tests operator associativity for the + operator when mixing numeric addition and String concatenation in Java. Evaluation proceeds left-to-right; once a String is involved in a + expression, concatenation rules apply for subsequent terms.

Given Data / Assumptions:

• i1 = 5, i2 = 6, s1 = "7".
• Expression is i1 + i2 + s1.
• println converts the final expression to a String.

Concept / Approach:
The + operator is left-associative. First compute 5 + 6 to produce the int 11. Then 11 + "7" triggers String concatenation, yielding "117".

Step-by-Step Solution:
Compute i1 + i2 = 5 + 6 = 11. Then 11 + s1 = 11 + "7" → "117". println prints "117".

Verification / Alternative check:
If you wrote i1 + (i2 + s1), then 6 + "7" becomes "67", and 5 + "67" becomes "567". Parentheses change the grouping and the result.

Why Other Options Are Wrong:
"18" would require conversion of "7" to int then addition; Java does not auto-parse String to int. "567" only happens with different grouping. No compiler error is present.

Common Pitfalls:
Forgetting left-to-right evaluation; assuming automatic String-to-int conversion exists.

Final Answer:
117
