public class Test {
private static int value=1;
public static void Main (string[] args)
{
int value=2;
System.out.println (value);
int x=100;
int y=200;
System.out.println ("x+y=" +x+y);
System.out.println (x+y+ "=x+y");
}
}

The operation results of the above procedure are as follows

found that ' + ' is sometimes an operator sometimes a connector at output

After the program has been modified
public class Test {
private static int value=1;
public static void Main (string[] args)
{
int value=2;
System.out.println (value);
int x=100;
int y=200;
System.out.println ("x+y=" +x+y);
System.out.println (x+y+ "=x+y" +x+y);
}
}

Run the result as

This shows that when the output is ' + ' before the first string is a plus sign, then the link number
