一句话说明==和equals的区别

public class equals {
    public static void main(String[] args) {
        int x=10;
        int y=10;
        String str1=new String("abc");
        String str2=new String("abc");
        System.out.println(x==y);//true
        System.out.println(str1==str2);//false
        System.out.println(str1.equals(str2));//true

    }
