4. Write the complete statement needed to declare and initialize a 2D integer array named nums with 5 rows and 2 columns. 5. The Math class has a static method named max that accepts two int arguments and returns the value of the larger one. Assume that two int variables, population 1 and population 2, have already been declared and initialized. Write an the complete statement needed to store the vale of the larger of population 1 and population2 in a new int variable named maxPopulation. Remember to use correct spacing. ); 6. Write a statement that reads a word from standard input into firstWord. Assume that first Word has already been declared as a String variable. Assume also that stdin is a variable that references a Scanner object associated with standard input.

Question

Hi,

I just have java attached problems that I need help understanding. Thanking you! 

### 4. Array Declaration and Initialization Write the complete statement needed to declare and initialize a 2D integer array named `nums` with 5 rows and 2 columns. ```java int[][] nums = new int[5][2]; ``` ### 5. Using Math Class Static Methods The `Math` class has a static method named `max` that accepts two `int` arguments and returns the value of the larger one. Assume that two `int` variables, `population1` and `population2`, have already been declared and initialized. Write the complete statement needed to store the value of the larger of `population1` and `population2` in a new `int` variable named `maxPopulation`. Remember to use the correct spacing. ```java int maxPopulation = Math.max(population1, population2); ``` ### 6. Reading Standard Input Write a statement that reads a word from standard input into `firstWord`. Assume that `firstWord` has already been declared as a `String` variable. Assume also that `stdin` is a variable that references a `Scanner` object associated with standard input. ```java firstWord = stdin.next(); ``` This layout explains the steps in a clear and concise manner, making it easy for students to understand and follow the statements required for array initialization, using static methods, and reading from standard input.
