Why are local variables not initialized in Java?

by

Local variables are declared mostly to do some calculation. So it’s the programmer’s decision to set the value of the variable and it should not take a default value.

If the programmer, by mistake, did not initialize a local variable and it takes a default value, then the output could be some unexpected value. So in case of local variables, the compiler will ask the programmer to initialize it with some value before they access the variable to avoid the usage of undefined values.
