You are not required to write a complete program.publicclassSumDivisibleBy3{publicstaticvoidmain(String[]args){intsum0;for(inti1;i100;i){if((i%3)0){sumi;}}System.out.println(sum);}}8.answer:double[]numbers{3.5,6,2.6,8.0};int[]marksnewint[60];char[]letters{a,b,c,d,e,f};String[]books{Java,SQL,PHP};9.output:Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 5at Test_Q2.main(Test_Q2.java:5)Reason:ishould less than intArray, rather than10.answer:f[1] new Flower();11.answer:ArrayIndexOutOfBoundsException12.answer:variable i might not have been initializedint i0;13.answer:3636.014.publicclassStarsTriangle{publicstaticvoidmain(String[]args){introw0;intsize8;while(rowsize){intcol0;while(colrow){System.out.print(*);colcol1;}System.out.println();rowrow1;}}}15.Determine the question that should result in the following possible answersAnswer 1“This happens when a class has multiple methods with the same name but different lists of parameters.It helps ensure consistency when naming methods.”Answer 2“Methods in the same class that share the same name but accept different variable types as arguments. Such methods give programmers the flexibility to call a similar method with different types of data.”answerWhat is method overloading in Java?
