It’s possible to nest one for-loop in another for-loop. This approach is used to process multidimensional structures like tables (matrices), data cubes, and so on. As an example, the following code prints the multiplication table of numbers from 1 to 9 (inclusive). for(inti=1;i<10;i...
/* 1*1=1 1*2=2 2*2=4 1*3=3 2*3=6 3*3=9 */ public class MultiplicationTable{ public static void main(String [] args){ for(int i=1;i<=9;i++){ for(int j=1;j<=i;j++){ System.out.print(j+"*"+i+"="+i*j+"\t"); } System.out.println(); } } } /* 1*1...

The above code will give the compile-time error because the for loop demands a boolean value in the second part and we are providing an integer value, i.e., 0.Core Java - OOPs Concepts: Initial OOPs Interview QuestionsThere is given more than 50 OOPs (Object-Oriented Programming and ...
在Java中,支持if/else和switch case两种选择结构,同时支持while,do...while,for循环以及JDK1.5以后支持foreach循环,同时还支持带标签的循环结构以及通过使用break,continue来中断循环。 4.2 使用Scanner类实现程序交互 平常在使用PC浏览电商网站时,如果想要购买商品通常需要输入用户名和密码来登录系统。

Looping Statements in Java Java has only 3 looping statements: while , do-while , and for. In Java we write i = 0; while ( i < 100) x = x + i++; } { The loop is executed as long as the condition in parentheses is true. It is possible that such a loop may never be ...
