1: public class Squares { 2: public static long square(int x) { 3: long y = x * (long) x; 4: x = -1; 5: return y; 6: } 7: public static void main(String[] args) { 8: int value = 9; 9: long result = square(value); 10: System.out.println(value); 11: } }
❌ A. -1 ✅ B. 9 ❌ C. 81 ❌ D. Compiler error on line 9. ❌ E. Compiler error on a different line
Explanation: Since Java is pass-by-value and the variable on line 8 never gets reassigned, it stays as 9. In the method square, x starts as 9. y becomes 81 and then x gets set to –1. Line 9 does set result to 81. However, we are printing out value and that is still 9.

Spiking bond yields driving sharp losses in tech stocks
A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year.
A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
