阅读下面程序 public class OperatorsAndExpressions { void equalsMethodl() { String s1=new String("how are you"); String s2=new String("how are you"); System.out.println(s1==s2); } public static void main(String args[]) { OperatorsAndExpressions perAndExp=new OperatorsAndExpressions(); //用于复合类型数据的“==”运算符 OperAndExp.equalsMethodl(); } } 程序运行的结果是A. ==B.trueC.falseD.equal
下面的程序执行后,屏幕上应显示______。 public class Test{ public static void main(String[ ]args){ char char1[ ]={'t','e','s','t'}; char char2[ ]={'t','e','s','t','1'}; String s1=new String(char1); String s2=new String(char2,0,4); System.out.println(s1.equals(s2)); } }A.trueB.falseC.testD.编译错误
阅读下面程序 public class OperatorsAndExpressions { void equalsMethodl(){ String s1=new String("how are you"); String s2=new String("how are you"); System.out.println(s1==s2); } public static void main(String args[]){ OperatorsAndExpressions perAndExp=new OperatorsAndExpressions(); OperAndExp.equalsMethod1(); } } 程序运行结果是( )。A. ==B.trueC.假D.equal
阅读下面程序 public class Operators And Expressions( void equals Methodl{ Stringsl一new String("how are you"); Strings2=new String("how are you"); System.out.println(s1= =s2): } public static void main(String args[]){ Operators And Expressions Oper And Exp=new Oper- ators And Expressions ; //用于复合类型数据的”= =”运算符 OperAndExp.equalsMethodl; } } 程序运行结果是( )。A.= =B.trueC.falseD.equal
9、请阅读下面的代码 String s1=new String(“abc”); String s2=s1.intern(); String s3=”abc”; System.out.println(s1==s2); System.out.println(s2==s3); System.out.println(s1==s3); 下列选项中,程序的输出结果为()A.false true falseB.false false falseC.false true trueD.false false true
分析下面的三行代码,创建了几个对象? () String s = new String("abc"); String s1 = "abc"; String s2 = new String("abc");A.1B.2C.3D.4
