Java Basic Road (iii)----Process Control statements

Today we're going to talk about process control in Java.

Let's start by talking about the SELECT statement.

There are two types of SELECT statements: 1, if statements. 2, switch statement;

The IF statement is divided into three kinds: if, if else, if elseif else.

The conditional statements in Java are consistent with C + +, and there is not much difference.

Simple If statement example code:

/**IF Conditional Statement "Sample code * Function: Enter three numbers, output maximum */Import Java.util.Scanner;PublicClass Program {PublicStaticvoid Main (String [] args) {int num1,num2,num3,Max Scanner input =New Scanner (system.in); System.out.println ( "Please enter first number:"); Num1=input.nextint (); System.out. println ( "Please enter a second number:"); Num2=input.nextint (); System.out. println ( "Please enter third number:"); Num3=input.nextint (); MAX=NUM1; if (Num2>max) {MAX=NUM2;} if (Num3>max) {MAX=NUM3;} System.out. println ( "max=" +max); input.< Span class= "hljs-built_in" >close (); }} 

                               Note: if: There is no relationship between a single branch structure   multiple if, it is executed sequentially. The 

                               if else   else must be related to its nearest if. 

                               If ElseIf else: there is a jumping off phenomenon.
