Java operators — which two expressions are equivalent among the following?\n\n1) 3/2\n2) 3<2\n3) 34\n4) 3<<2\n\nAssume integer arithmetic and Java precedence.

Introduction / Context:
This question compares basic arithmetic with shift operations to see which yield the same result for constant integers, reinforcing that left shift by n multiplies by 2^n for non-overflowing operands.

Given Data / Assumptions:

• All literals are int.
• Left shift by 2 equals multiply by 4 when no overflow occurs.

Concept / Approach:
Evaluate each expression: integer division truncates, comparison yields boolean, multiplication is straightforward, and left shift scales by a power of two. Compare the numeric outcomes for equality.

Step-by-Step Solution:

Verification / Alternative check:
Binary form: 3 is 0b0011; shifting left by 2 → 0b1100 = 12, matching 3*4.

Why Other Options Are Wrong:

• Options with 1 or 2 cannot equal 12; 1 is 1 and 2 is boolean.

Common Pitfalls:
Forgetting that << is arithmetic scaling for non-overflowing positive ints; also mixing boolean and numeric expressions.

Final Answer:
3 and 4
