Expressions and Output() - AP Computer Science A

1. Integer division truncates the decimal portion in Java.

2.6666666666666665. Double division produces precise floating-point result.

1. Character '2' concatenates, then numeric addition occurs.

1. Character 'a' has ASCII value 97, so $97 + 1 = 98$.

1. Order: $2 \times 3 = 6$, then $4 + 6 - 1 = 9$.

Using escape sequence ". Backslash escapes special characters in string literals.

2.0. Double dividend produces floating-point division.

1. ASCII values: a=97, b=98, so $97 + 98 = 195$.

1. Integer division truncates the decimal portion.

Operator '-' cannot be applied to Strings. Subtraction operator is not defined for String operands.

false. Floating-point arithmetic precision issues cause inequality.

1. Modulus operator returns the remainder after division.

Java12. String concatenation evaluates left-to-right without grouping.

1. Multiplication precedence: $2 \times 3 = 6$, then $5 + 6 = 11$.

4.5. Double divisor produces floating-point division result.

1. Parentheses force addition first: $(3 + 4) = 7$, then $2 \times 7 = 14$.

2.0. Integer multiplied by double results in double type.

char. Stores a single Unicode character in 16 bits.

2.6666666666666665. Double division produces precise floating-point result.

2.0. Double dividend produces floating-point division.

false. Second condition is false, making the entire AND expression false.

Operator '-' cannot be applied to Strings. Subtraction operator is not defined for String operands.

1.5. Double division produces a floating-point result.

Output is 'Sum: 53', not 'Sum: 8'. String concatenation with $+$ operator evaluates left-to-right without parentheses.

char. Stores a single Unicode character in 16 bits.

1. Multiplication precedence: $3 \times 4 = 12$, then $2 + 12 = 14$.

false. Floating-point arithmetic precision issues cause inequality.

1. Integer division truncates the decimal portion.

2.0. Integer multiplied by double results in double type.
