Given integers representing the numerator and denominator of a fraction, return the fraction in string format.If the fractional part was repeating, enclose the repeating part in parentheses.For example,Given numerator = 1, denominator = 2, return "0.5".Given numerator = 2, denominator = 1, return "2".Given numerator = 2, denominator = 3, return "0. (6) ".Problem Solving Ideas:A variety of critical values wi

The Set calculator assists Java in processing conditional filtering of structured text, and java structuring
Using Java to filter data in text files by conditions may cause the following troubles:
1. files are not databases and cannot be accessed using SQL. When the filter conditions change, you must rewrite the code.
The Set calculator assists java in processing the alignment connection of structured text, and java structuring
The database has associated statements to facilitate alignment and join operations. However, sometimes data is stored in text files. To use JAVA for direct computation, you need to write a large number of loo
The Set calculator assists java in processing Structured Text Data Reading, java structured
JAVA only provides the most basic data reading functions such as specifying delimiters. Other common functions must be implemented at the underlying layer. For example: reads a specified column by column name, the sequence of th
The Set calculator assists Java in processing grouping and summarizing structured text, and java structuring
Using Java to group and summarize style files may cause the following troubles:
1. files are not databases and cannot be accessed using SQL. When the grouping and summary expressions change, you can only rewrite
The Set calculator assists java in processing the set operation of structured text, and java structuring
JAVA does not directly support set operations. Therefore, you must use nested loops to perform set operations such as intersection, union, and difference sets between text files. If there are many files, or if the f

To write an application that simulates a calculator, using the Panel and grid layout, add a text box, 10 number buttons (0~9), 4 subtraction buttons, an equal sign button, a purge button, a square root button, a backspace button that asks the calculation formula and results to be displayed in a text box. The implementation effect is shown in the following illustration.
