Question: How do you declare two variables in one line in Java?

How do you create multiple variables in a single statement?

double a=3, b=5.2, c=3.5/3.5; One more aspect is, while you are preparing common type variable in same line then from right assigned variables you can assign variable on left, for instance : int a = 4, b = a+1, c=b*b; Noticed, you can also practice arithmetic operations on variable by remaining in the same line.

How do you declare two variables?

How do I make two variables equal in Java?

In Java, an assignment statement can make two variables equal, but they don’t have to stay that way.

Taken together, the variables in a program and their current values make up the program’s state.

How many variables can you declare in one line?

Can you define multiple variables in one line?

Declaring multiple variables in a single declaration can cause confusion regarding the types of the variables and their initial values. If more than one variable is declared in a declaration, care must be taken that the type and initialized value of the variable are handled correctly.
