Скачать или смотреть Java Integer Math—Why 1 / 2 Gives 0, Not 0.5! 🎯

📢 Description:
Let’s break down this code and understand why the output is 1.0!

Problem:
What is the output of the following code?

java
Copy
int a = 7;
int b = 4;
double c;
c = a / b;
System.out.println(c);
Options:
A) 1.0
B) 1.75
C) 2.0
D) An error occurs because c was not initialized.

Quick Breakdown:
1️⃣ Integer Division:

Both a and b are integers, so when a / b is calculated, it performs integer division. This means the decimal part is ignored.
7 / 4 results in 1, since integer division truncates any remainder.
2️⃣ Conversion to Double:

The result of the division (1) is stored in c, which is of type double. Java automatically converts the integer value 1 to 1.0 when assigning it to a double.
3️⃣ Answer:

The correct output is Option A: 1.0.
🚀 Key Takeaways:

Integer division truncates the decimal part.
Java converts integer results to double when stored in a double variable.
