: These public, protected and private, these can be applied to class, variables, constructors and methods. But if you don�t specify an access modifier then it is considered as Friendly. In Core Java, access modifiers are keywords that determine the visibility or accessibility of classes, methods, and fields in a Java program. There are four … Read more

In case of signed left shift >> the new bits are set to zero. But in case of signed right shift it takes the value of most significant bit before the shift, that is if the most significant bit before shift is 0 it will introduce 0, else if it is 1, it will introduce … Read more

: 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
