1) Simple Java if-else example The following example shows how to use theif-elsestatement to display different messages based on the value of a variabletemperature: publicclassApp{publicstaticvoidmain(String[] args){inttemperature =25;if(temperature >30) { System.out.println("It's hot outsid...
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...
if(condition){//statement-1} 2. The If-else Example Let’s see an example of anif-elsestatement. In the following program, we check whether the employee’s age is greater than 18. On both bases, we print that the employee is a minor or an adult. intage=employee.getAge();if(age>...
publicclassIfStatementExample { publicstaticvoidmain(String args[]){ intnum=70; if( num < 100){ /* This println statement will only execute, * if the above condition is true */ System.out.println("number is less than 100"); } } } 输出: 1number is less than 100 2)Java中的嵌套if...

Example 1: Basicif...elseStatement publicclassIfElseExample{publicstaticvoidmain(String[]args){intnumber=10;if(number>0){System.out.println("The number is positive.");}else{System.out.println("The number is not positive.");}}} In this example, the program checks if thenumberis greater ...
We can also check for vowel or consonant using a switch statement in Java. Example 2: Check whether an alphabet is vowel or consonant using switch statement public class VowelConsonant { public static void main(String[] args) { char ch = 'z'; switch (ch) { case 'a': case 'e': cas...
if-else 就是一个语句,可以是另一个语句的一部分,也可以是 if-else 的一部分,即嵌套。 求a,b,c三个数的最大数。 publicclassExample2 {publicstaticvoidmain(String[] args) {inta = 100;intb = 100;intc = 23;//分这几种情况:abc等大;a最大;b最大;c最大;ab等大并且最大;ac等大并且最大;bc...
Example: Python if Statement number = int(input('Enter a number: '))# check if number is greater than 0ifnumber >0:print(f'{number}is a positive number.')print('A statement outside the if statement.') Run Code Sample Output 1 ...
