我们编译间套里面的if else时,把内部的ifelse对应的分支名称在前面加上i,比如一层间套,那么它对应的就是ibranch0,两层就是iibranch0,同理一层间套对应iout_branch0,两层就是iiout_branch0. 由于存在间套原因,ifelse语句编译比较困难,且容易出错。我们看看实现编译的代码实现,首先是修改program_generator.java:...

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...
In the above program, instead of using a long if condition, we replace it with a switch case statement. If ch is either of cases: ('a', 'e', 'i', 'o', 'u'), vowel is printed. Else, default case is executed and consonant is printed on the screen. Also Read: Java Program to...
These are simplified examples that show how to use the If-Else statement effectively. Another popular conditional statement used in Java programs is the If-Else If statement. This allows your program to test for more than two choices in a single If-Else statement. In fact, an If-Else If ...
