what is this int a+=1

[kapil456]

what is this means int a+=1 in java

[clyo cleopas]

It means int a = a + 1;

[111100/11000]

that should mean:

int a = a + 1;

but it should be also an error if you try to add 1 to uninitialized a if a is local variable of a method
however if a is a class variable than it is initialized by default to 0 so this code would make it 1
