equals与”==”的区别

String personalLoan = new String("cheap personal loans");
String homeLoan = new String("cheap personal loans");

//since two strings are different object result should be false
boolean result = personalLoan == homeLoan;
System.out.println("Comparing two strings with == operator: " + result);

//since strings contains same content , equals() should return true
result = personalLoan.equals(homeLoan);
System.out.println("Comparing two Strings with same content using equals method: " + result);

homeLoan = personalLoan;
//since both homeLoan and personalLoand reference variable are pointing to same object
//"==" should return true
result = (personalLoan == homeLoan);
System.out.println("Comparing two reference pointing to same String with == operator: " + result);

Output:
Comparing two strings with == operator: false
Comparing two Strings with same content using equals method: true
Comparing two reference pointing to same String with == operator: true
