JAVA Process Control Selection statement

In programming, there are three basic techniques that can change the process control of a program:

1. Call method;
2. Select
3. Cycle.

Here, we mainly talk about the choice statement.

The selection statements in Java are essentially the same as in C, including:

1. If statement;
2. If/else statement;
3. Switch statement.

If statement:

1 if (Boolean expression) {2     // if the Boolean expression in parentheses after the If is true, the statement    here is executed 3 }

If/else statement:

1 if (Boolean expression) {2     // executes the statement here when the Boolean expression is true for the if post-parenthesis; 3 }else{4     // Executes the statement here when the Boolean expression is false in parentheses after the IF. 5 }

Or

if(Boolean expression) {//executes the statement here when the Boolean expression is true for the if post-parenthesis;}Else if(Boolean expression) {//executes the statement here when the Boolean expression is false in parentheses after this else if;}Else if(Boolean expression) {//executes the statement here when the Boolean expression is false in parentheses after this else if;}Else if(Boolean expression) {//......}Else{    //The above conditions are not satisfied when the implementation;}

Switch statement:

The switch statement allows the variable to be tested for equality with multiple values, and the switch statement generally has the following format:

1 Switch(variable) {2      Casevalue 1:3 statement;4          Break;//options available5      Casevalue 1:6 statement;7          Break;//options available8     .9     .Ten     . One     . A     . -     . -  CaseValue N: the statement; -          Break;//options available - default://default Optional - statement; +// Break;//options available -}

At this point, the three selection statements for Java Process Control are complete.
