What is used in Java to represent it?

In Java, the logical operator “&&” is used to represent “and”. This operator is used to check if multiple conditions are true at the same time, with the result being true only if all conditions are true. For example:

int a = 5;
int b = 10;

if (a > 0 && b > 0) {
    System.out.println("a和b都大于0");
}

In the code above, if both a and b are greater than 0, the conditional expression “a > 0 && b > 0” will result in true, which will execute the code block within the if statement that outputs “a and b are both greater than 0”. Otherwise, the output statement will not be executed.
