does anyone know why:
if (false && true || true) {
System.out.println("True");
} else {
System.out.println("False");
}
Print "True"
if (false && true | true) {
System.out.println("True");
} else {
System.out.println("False");
}
Print "False"

The key difference between Bitwise and Logical operators is that Bitwise operators work on bits and perform bit by bit operations while logical operators are used to make a decision based on multiple conditions.
No. First, using bitwise operators in contrast to logical operators is prone to error (e.g., doing a right-shift by 1 is NOT equivalent to multiplying by two). Second, the performance benefit is negligible (if any).
Both of them combine Boolean values ( true/false values ) into one Boolean value. But each does this in a different way: All the values AND combines must be true to get a true. At least one of the values OR combines must be true to get a true.
“Logical not or !” is meant for boolean values and “bitwise not or ~” is for integers. Languages like C/C++ and python do auto promotion of boolean to integer type when an integer operator is applied. But Java doesn't do it.
In the first case && has higher precedence than || operator so the expression is evaluated as if ( (false && true) || true ) and you get True.
In the second case bitwise OR operator has higher precedence than && so the expression is evaluated as if ( false && ( true | true ) ) and you get False.
