No. It is not a valid java operator.
No, &&= is not a valid Java operator. In Java, there is no &&= operator. The && operator is used for logical AND operations, but it is not combined with the assignment operator = in this manner.
Valid examples of logical AND in Java include:
java
boolean result = (a && b);
This checks if both a and b are true. However, there is no compound assignment operator like &&= in Java.
