In Java, if statement is used for testing the conditions. The condition matches the statement it returns true else it returns false. There are four types of If statement they are: 在Java中,if语句用于测试条件。 条件与返回true的语句匹配,否则返回false。 有四种类型的If语句: For example, if we...
1.if then else if-else语句是控制程序流程的最基本的形式,其中else是可选的。基于此就会存在下列三种形式。 1.存在else的表达式 if(布尔表达式) { 代码 } else { 代码 } 1. 2. 3. 4. 5. 2.不存在else的表达式 if(表达式) { 代码 } 1. 2. 3. 注:在代码中常出现的else if并不是什么新语句,而...
compareTo(bd3); if (result1 < 0) { System.out.println("bd1小于bd2"); } else if (result1 > 0) { System.out.println("bd1大于bd2"); } else { System.out.println("bd1等于bd2"); } if (result2 == 0) { System.out.println("bd1等于bd3"); } } } 在这个例子中,compareTo...

boolean even; if (number % 2 == 0) even = true; else even = false;Code 2:boolean even = (number % 2 == 0); A)Code 1 has compile errors. B)Both Code 1 and Code 2 are correct, but Code 2 is better. C)Both Code 1 and Code 2 have compile errors. D)Code 2 has compile...
The next condition, in the else if statement, is also false, so we move on to the else condition since condition1 and condition2 is both false - and print to the screen "Good evening".However, if the time was 14, our program would print "Good day."...
