JAVA 第一节练习

任务一：在控制台输出： Wonderful Java world

public class Exercise1 {
	public static void main(String[] args) {
		//控制台输出
		System.out.println("Wonderful Java world");
	}
 }

任务二：使用转义符在控制台输出扑克牌的样式

public class Exercise2 {
	public static void main(String[] args) {
		System.out.print("* * * * * * * * *\n");
		System.out.print("* 10\t\t*\n");
		System.out.print("*\t\t*\n");
		System.out.print("*\t\t*\n");
		System.out.print("*\t◇\t*\n");
		System.out.print("*\t\t*\n");
		System.out.print("*\t\t*\n");
		System.out.print("*            10 *\n");
		System.out.print("* * * * * * * * *\n");
	}
   }

任务三：使用转义符“\n”和“\t”打印课程表

public class edd {
	public static void main(String[] args) {
		System.out.println("                                     课程表\n");
		System.out.print("\t时间");
		System.out.print("\t8:00-10:00");
		System.out.print("\t10:10-12:00");
		System.out.print("\t1:30-3:30");
		System.out.print("\t3:40-5:40\n");
		System.out.print("\t星期一");
		System.out.print("\tJAVA");
		System.out.print("\t           C#");
		System.out.print("\t           SQL");
		System.out.print("\t            HTML\n");
		System.out.print("\t星期二");
		System.out.print("\tC#");
		System.out.print("\t           SQL");
		System.out.print("\t           HTML");
		System.out.print("\t            JAVA\n");
		System.out.print("\t星期三");
		System.out.print("\tSQL");
		System.out.print("\t           HTML");
		System.out.print("\t           JAVA");
		System.out.print("\t            C#\n");
		System.out.print("\t星期四");
		System.out.print("\tHTML");
		System.out.print("\t           JAVA");
		System.out.print("\t           C#");
		System.out.print("\t            SQL\n");
		System.out.print("\t星期五");
		System.out.print("\tC#");
		System.out.print("\t           JAVA");
		System.out.print("\t           SQL");
		System.out.print("\t           HTML");
		
		
		
	}
