Java language overview

I personally believe that the basis for learning a programming language is to learn from demos.

Practice the console output tool. System.out.println outputs newlines, and System.out.print outputs no newlines.

package com;
public class Test {
public static void main(String[] args) {
System.out.println("hello, Tang Huimin.");
System.out.println(args[0]);
System.out.println(args[1]);
}
}

Configuration parameter args:

Run result:

package com;
public class Test {
public static void main(String[] args ) {
System.out.print("hello, Tang Huimin.");
System.out.print(args[0]);
System.out.print(args[1]);
}
}

Run result:

Output a triangle composed of "*"

package com;
public class Test {
public static void main(String[] args) {
System.out.println(" *");
System.out.println(" ***");
System.out.println("*****");
System.out.println("*****");
}
}

Run result:

Output symbol expression

package com;
public class Test {
public static void main(String[] args ) {
System.out.println(" ╭︿︿︿╮ ");
System.out.println(" {/ o o /}");
System.out.println(" ( (oo) )");
System.out.println(" ︶ ︶︶");
}
}

Result:
