Java 程序打印前 10 个奇数自然数

使用 for 循环编写一个 Java 程序来打印前 10 个奇数自然数。

package NumPrograms;

public class First10OddNaturalNum1 {

	public static void main(String[] args) {
		
		System.out.println("The First 10 Odd Natural Numbers are");
		for(int i = 1; i <= 10; i++) 
		{
			System.out.println(2 * i - 1);
		}
	}
}

Java Program to Print First 10 Odd Natural Numbers

此 Java 程序使用 while 循环打印前 10 个奇数自然数。

package NumPrograms;

public class First10OddNaturalNum2 {

	public static void main(String[] args) {
		int i = 1;
		
		System.out.println("The First 10 Odd Natural Numbers are");
		
		while( i <= 10) 
		{
			System.out.println(2 * i - 1);
			i++;
		}
	}
}

The First 10 Odd Natural Numbers are
1
3
5
7
9
11
13
15
17
19

此 Java 示例代码使用 do while 循环打印前 10 个奇数自然数。

package NumPrograms;

public class First10OddNaturalNum3 {

	public static void main(String[] args) {
		int i = 1;
		
		System.out.println("The First 10 Odd Natural Numbers are");
		
		do
		{
			System.out.println(2 * i - 1);

		} while(++i <= 10);
	}
}

The First 10 Odd Natural Numbers are
