Technical Interview Questions
: They are discarded In Core Java, when you perform bitwise shifting operations (left shift << or right shift >>), the bits that “fall off” or go beyond the boundaries of the variable are discarded. For left shift (<<), zeros are filled in from the right, and for right shift (>>), the sign bit (the … Read more
No, shift operators can be applied only to integer or long types No, shift operators cannot be applied directly to float types in Java. Shift operators (<<, >>, >>>) are bitwise operators that operate on integer types (byte, short, int, long). They manipulate the binary representation of the integer values by shifting the bits to … Read more
Ans: It converts all the 1 bits in a binary value to 0s and all the 0 bits to 1s, e.g 11110000 coverts to 00001111 The bitwise NOT operator (~) in Java is a unary operator that inverts the bits of its operand. It flips each bit of the operand from 0 to 1 and … Read more

: No No, both System.gc() and Runtime.gc() in Java do not guarantee garbage collection. These methods suggest to the JVM (Java Virtual Machine) that it would be a good time to perform garbage collection, but the decision to actually perform garbage collection is ultimately left to the JVM’s discretion. The JVM is free to ignore … Read more
