How to output java string

In Java programming, we often use System.out.println(); to output strings.

System.out.println();

System is a class, inherited from the root class Object

out is an object instantiated by the PrintStream class. And it is a static member variable of the System class

println() is a member method of the class PrintStream and is called by the object out

package Number;
public class Frust {
	//声明 静态的   字符串变量 ，不大明白 静态是啥意思
	static String s1 = "你好";
	public static void main(String[] args) {
		// TODO 自动生成的方法存根
		//声音一个 字符串变量
		String s2 = "Java";
		//输出 S1 + S2 字符串
		System.out.println(s1 + s2);
		//输出 S1  字符串
		System.out.println(s1 );
		//输出 S2 字符串
		System.out.println(s2);
	}
}
