在这里，我们将编写两个 java 程序来查找三个数字中最大的程序。 1）使用if-else..if2）使用嵌套的If
示例 1：使用if-else..if查找三个数字中的最大数字
public class JavaExample{ public static void main(String[] args) { int num1 = 10, num2 = 20, num3 = 7; if( num1 >= num2 && num1 >= num3) System.out.println(num1+" is the largest Number"); else if (num2 >= num1 && num2 >= num3) System.out.println(num2+" is the largest Number"); else System.out.println(num3+" is the largest Number"); }}输出：
20 is the largest Number
示例 2：使用嵌套if在三个数字中查找最大数字
public class JavaExample{ public static void main(String[] args) { int num1 = 10, num2 = 20, num3 = 7; if(num1 >= num2) { if(num1 >= num3) /* This will only execute if conditions given in both * the if blocks are true, which means num1 is greater * than num2 and num3 */ System.out.println(num1+" is the largest Number"); else /* This will only execute if the condition in outer if * is true and condition in inner if is false. which * means num1 is grater than num2 but less than num3. * which means num3 is the largest */ System.out.println(num3+" is the largest Number"); } else { if(num2 >= num3) /* This will execute if the condition in outer if is false * and inner if is true which means num3 is greater than num1 * but num2 is greater than num3\. That means num2 is largest */ System.out.println(num2+" is the largest Number"); else /* This will execute if the condition in outer if is false * and inner if is false which means num3 is greater than num1 * and num2\. That means num3 is largest */ System.out.println(num3+" is the largest Number"); } }}输出：
20 is the largest Number
