Java程序设计 int nNuml =6 int nNum2 =8 System. out printIng nNum1不自加短路原则 System. out. println((nNuml <nNum2)&&(--nNum1)>nNum2)) System. out printIn("nNumI is"+nNumI System. out. printin( ((nNumI <nNum2)&&(--nNuml)>nNum2)) System. out println("nNuml is"+nNum1) §1.3流程控制语句 1.Whle与 Do. While语句的区别是什么? 2.下面程序的输出结果是什么? public class My First public static void main( String args) ntx=l,y, total =0; System. out println(y=+y) System. out. println("Total is "+total) 3.设计程序求1到100的和。 4.请指出下面程序的错误 swith(n) System. out. printIn("First)Java 程序设计 - - 3 - int nNum1 = 6; int nNum2 = 8; System.out.println(); //nNum1 不自加短路原则 System.out.println(((nNum1 < nNum2) && (--nNum1) > nNum2)); System.out.println("nNum1 is " + nNum1); System.out.println(((nNum1 < nNum2) && (--nNum1) > nNum2)); System.out.println("nNum1 is " + nNum1); } §1.3 流程控制语句 1．While 与 Do…While 语句的区别是什么？ 2．下面程序的输出结果是什么？ public class MyFirst { public static void main(String args[]) { int x = 1,y,total = 0; while(x <= 20) { y = x * x; System.out.println(“y = “ + y); total = total + y; ++x; } System.out.println(“Total is “ + total); } } 3．设计程序求 1 到 100 的和。 4．请指出下面程序的错误： swith(n) { case 1 : System.out.println(“First”);
