The truth table of elementary logic operations (AND, OR, and XOR) looks as follows:

In Java, the logical AND operator is represented as &&, the logical OR operator is represented as ||, and the logical XOR operator is represented as ^. Starting with JDK 8, these operators are applied to two booleans and are wrapped in three static methods—Boolean.logicalAnd(), Boolean.logicalOr(), and Boolean.logicalXor():

int s = 10;
int m = 21;

// if (s > m && m < 50) { } else { }
if (Boolean.logicalAnd(s > m, m < 50)) {} else {}
 
// if (s > m || m < 50) { } else { }
if (Boolean.logicalOr(s > m, m < 50)) {} else {}

// if (s > m ^ m < 50) { } else { }
if (Boolean.logicalXor(s > m, m < 50)) {} else {}

Using a combination of these methods is also possible:

if (Boolean.logicalAnd(
    Boolean.logicalOr(s > m, m < 50),
    Boolean.logicalOr(s <= m, m > 50))) {} else {}
