Here's a bunch of examples to illustrate the immutability of Java's string.1. Declare a strings = "abcd";The s variable holds a reference to the string object, and the following arrows explain the reference to which object is saved.2. Assign a string variable to another string variable.s;The string object cannot be changed to show 2 variables s2 Save the same referenced values, which point to the value of the same object.3. connect strings = s.concat("ef");The variable s now holds a reference to

1. All the numbers in the program are stored in binary form in the computer's memory . Bitwise arithmetic is the direct operation of an integer in memory bits. 2. And operation: only the first and the two operands are 1 and the result is 1. 3. Or operation: 1 bits are 1, and the result is 1.4. XOR: Not the same is 1.5. Take the inverse operation: Change 1 to 0 and 0 to 1.6. Shift operation: Shift left is multiply by 2, and right moves except 2. Discard if the boundary is exceeded.Speaking

also often used to find the number K in a series. Only a minimum heap of size k is required, and the top of the heap is the number of K-large. If we ask for a small number of K in a series, we only need to build a maximum heap of k, and the heap top is the small number of K, the time complexity of this method is O (NLOGK). Of course, you can also use the heap to find the first K large number and the first k small number. Can you think of a faster algorithm? Interested students can read the seco
