Basic java programming

Pt 1. Write a JAVA program to identify the minimum of two numbers a and b, where a= 10, b=3 using the Math function

Pt.2 Design a flowchart to determine the grade of a student based for the scores provided below:

MarksGrade

>=90 A

>=80 B

>=70 C

>=60 D

>=50 F

Pt. 3 Write a JAVA program using if/else statements to determine the grade of a student for the scores provided below:

MarksGrade

>=90 A

>=80 B

>=70 C

>=60 D

>=50 F

Pt.4 The output of this code is 2, what changes should be done to get the output as 8.

public static void calculate ()

{

int i = 42 + 45 -48 -5;

int j = 5 + 5 8 + 2;

int ans = i % j;

System.out.println (Value of Ans = + ans);

}
