L3, Basics of Java Syntax, Usage of Spaces and Tabs, package q10798

Spaces and Tabs are very important for code formatting.

An empty space is used as a separator between two tokens. A tab ———  is used only to indent lines.

Whenever a new block of code starts after the opening brace { the lines inside that block should be indented by one level (one level means by one tab) compared to the line which contains the opening brace {.

Note: Usually after a opening brace {, we press the ENTER ¬  key to go to next line, where a tab is automatically inserted for indentation.

Below example shows the usage of spaces and tabs:

public class SpacesAndTabsDemo {

———public static void main(String[] args) {

——————for (int i = 0; i < 5; i++) {

—————————System.out.println("i = " + i);

——————}

———}

}

orange borders mark spaces

——— pink borders mark tabs

See and retype the below code, make sure to use spaces and tabs appropriately.

package q10798 :-

package q10798;
public class SpacesAndTabsDemo {
    public static void main(String[] args) {
        for (int i = 0; i < 5; i++) {
            System.out.println("i = " + i);
        }
    }
}
