Java 查找数字平方的程序

编写一个 Java 程序，使用方法和示例查找数字的平方。

Java 查找数字平方示例 1

这个 Java 程序允许用户输入一个整数值。然后，这个 Java 程序使用算术运算符计算该数字的平方。

// Java Program to Find Square of a Number
import java.util.Scanner;

public class SquareofNumber {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int number, square;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		number = sc.nextInt();		
		
		square = number * number;
		
		System.out.println("\n The Square of a Given Number  " + number + "  =  " + square);
	}
}

Java 查找数字平方示例 2

这个Java 程序与上面的程序相同。但这一次，我们创建了一个单独的 Java 方法来计算该数字的平方。

// Java Program to Find Square of a Number
import java.util.Scanner;

public class SquareofNumber1 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int number, square;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		number = sc.nextInt();	
	
		// Calling below static method calsqaure
		square = calsquare(number);
		
		System.out.println("\n The Square of a Given Number  " + number + "  =  " + square);
	}
	
	public static int calsquare(int num)
	{
		return num * num;
	}
}

Java 数字平方输出

 Please Enter any Number : 64

 The Square of a Given Number  64  =  4096
