how does multiplication works in Java

In Java, multiplication is performed using the * operator. When the * operator is used with two operands, it multiplies the operands and returns the result.

For example, the following code multiplies two int variables and assigns the result to a third int variable:

int a = 2;
int b = 3;
int c = a * b; // c is now 6

The * operator can also be used with other numeric data types, such as float, double, and long. For example:

float d = 2.5f;
float e = 3.0f;
float f = d * e; // f is now 7.5

double g = 2.5;
double h = 3.0;
double i = g * h; // i is also 7.5

In these examples, the * operator multiplies the operands and returns the result as the same data type as the operands.

Keep in mind that the * operator has a higher precedence than most other arithmetic operators in Java, which means that it will be evaluated before other operators in an expression.
